Often there is a need to convert hours to minutes or minutes to seconds. And if there are usually no problems with such quantities as weight and length, then over time people for some reason get confused. Well, for example, 1.7 kilometers is immediately clear that it is 1,700 meters. 1.16 kilograms is 1160 grams. But 2.47 hours is not 2 hours and 47 minutes, and not even 247 minutes. How then to translate? I'll explain now.

Convert hours to minutes and vice versa:

Problems when converting time arise because we multiply by the wrong number or simply omit commas altogether, as in the example above. You just need to remember this: there are 60 minutes in one hour. And therefore, in order to represent hours as minutes, you need to multiply them by 60.

2 hours = 2 * 60 = 120 minutes

4.28 hours = 4.28 * 60 = 256.8 minutes

And if you need to convert minutes back to hours, then you need to divide the number of minutes by 60:

138 minutes = 138 / 60 = 2.3 hours

240 minutes = 240 / 60 = 4 hours

Convert minutes to seconds and vice versa:

We translate in the same way as described above. Because there are also 60 seconds in one minute.

7 minutes = 7 * 60 = 420 seconds

6.2 minutes = 6.2 * 60 = 372 seconds

The reverse conversion of seconds to minutes is the same. Divide the number of seconds by 60.

186 seconds = 186 / 60 = 3.1 minutes

72.6 seconds = 72.8 / 60 = 1.21 minutes

Convert hours to seconds and vice versa:

Based on the knowledge gained above, this is also easy to do. 1 hour = 60 minutes = 3600 seconds. Therefore, the hours must be multiplied by 3600.

2.8 hours = 2.8 * 3600 = 10080 seconds

3.18 hours = 3.18 * 3600 = 11448 seconds

Converting seconds to hours is no different. Divide the seconds by 3600.

7425 seconds = 7425 / 3600 = 2.0625 hours

9612 seconds = 9612 / 3600 = 2.67 hours

Now, I hope, converting one unit of time to another will not cause you any difficulties.

When working with time in Excel, sometimes the problem arises of converting hours to minutes. It would seem to be a simple task, but it is often too difficult for many users. But the point is all in the peculiarities of calculating time in this program. Let's figure out how you can convert hours to minutes in Excel in various ways.

The whole difficulty of converting hours into minutes is that Excel calculates time not in the usual way for us, but in days. That is, for this program 24 hours are equal to one. The program represents the time 12:00 as 0.5, because 12 hours is 0.5 part of the day.

To see how this happens in an example, you need to select any cell on the sheet in time format.

And then format it to fit the general format. It is the number that appears in the cell that will reflect the program’s perception of the entered data. Its range can vary from 0 to 1 .

Therefore, the issue of converting hours into minutes must be approached precisely through the prism of this fact.

Method 1: Apply the multiplication formula

The simplest way to convert hours to minutes is to multiply by a certain factor. We found out above that Excel perceives time in days. Therefore, to obtain minutes from the expression in hours, you need to multiply this expression by 60 (number of minutes in hours) and on 24 (number of hours in a day). Thus, the coefficient by which we will need to multiply the value will be 60×24=1440. Let's see how this will look in practice.

1. Select the cell that will contain the final result in minutes. We put up a sign «=» . Click on the cell in which the clock data is located. We put up a sign «*» and type the number from the keyboard 1440 . In order for the program to process the data and display the result, click on the button Enter.



2. But the result may still be incorrect. This is due to the fact that, when processing time format data through a formula, the cell in which the total is displayed itself acquires the same format. In this case, it must be changed to general. To do this, select the cell. Then move to the tab "Home", if we are in a different one, and click on the special field where the format is displayed. It is located on the ribbon in the toolbox "Number". In the list that opens, among the many values, select the item "General".



3. After these steps, the correct data will be displayed in the specified cell, which will be the result of converting hours to minutes.



4. If you have not one value, but a whole range to convert, then you can not do the above operation for each value separately, but copy the formula using the fill marker. To do this, place the cursor in the lower right corner of the cell with the formula. We wait until the fill marker is activated in the form of a cross. Clamp left button mouse and drag the cursor parallel to the cells with the data being converted.



5. As we see, after of this action the entire series will be converted to minutes.



Method 2: Using the CONVERT function

There is also another way to convert hours to minutes. To do this, you can use a special function CONVERT. Please note that this option will only work when the original value is in a cell with a common format. That is, 6 hours should not be displayed as "6:00", but how "6", but 6 hours 30 minutes, not like "6:30", but how "6.5".






As you can see, converting hours to minutes is not as simple a task as it seems at first glance. This is especially problematic with data in time format. Fortunately, there are ways to make the transformation in this direction. One of these options involves the use of a coefficient, and the second - a function.

Many events are presented in minutes. But often, for ease of perception or some further calculations, it is necessary to represent these minutes in hours. How to do this? Read the instructions.

As you can see, converting minutes to hours is quite simple. You just need to remember the rules of multiplication, division and subtraction.

More about time

General information. Physical properties of time

Time can be viewed in two ways: how mathematical system, created to help our understanding of the Universe and the flow of events, or as a dimension, part of the structure of the Universe. In classical mechanics, time does not depend on other variables and the passage of time is constant. Einstein's theory of relativity, on the contrary, states that events that are simultaneous in one frame of reference can occur asynchronously in another if it is in motion relative to the first. This phenomenon is called relativistic time dilation. The above-described difference in time is significant at speeds close to the speed of light, and has been experimentally proven, for example, in the Hafele-Keating experiment. Scientists synchronized five atomic clocks and left one motionless in the laboratory. The remaining watches flew around the Earth twice on passenger planes. Hafele and Keating found that traveling clocks lag behind stationary clocks, as predicted by the theory of relativity. The effect of gravity, as well as increasing speed, slows down time.

Measuring time

Clocks define the current time in units smaller than one day, while calendars are abstract systems that represent longer time intervals such as days, weeks, months and years. The smallest unit of time is the second, one of the seven SI units. The standard of a second is: “9192631770 periods of radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom.”

Mechanical watch

Mechanical clocks typically measure the number of cyclic oscillations of events of a given length, such as the oscillation of a pendulum, which swings once per second. A sundial tracks the movement of the Sun across the sky throughout the day and displays the time on a dial using a shadow. Water clocks, widely used in antiquity and the Middle Ages, measure time by pouring water between several vessels, while hourglasses use sand and similar materials.

The Long Now Foundation in San Francisco is developing a 10,000-year clock called the Clock of the Long Now, which is designed to last and remain accurate for ten thousand years. The project is aimed at creating a simple, understandable and easy-to-use and repair design. No precious metals will be used in the construction of the watch. The design currently requires human operation, including winding the watch. Time is kept by a dual system consisting of an imprecise but reliable mechanical pendulum and an unreliable (due to weather) but accurate lens that collects sunlight. At the time of writing (January 2013), a prototype of this watch is being built.

Atomic clock

Currently, atomic clocks are the most accurate time measuring instruments. They are used to ensure accuracy in radio broadcasting, global navigation satellite systems, and worldwide accurate time measurement. In such clocks, the thermal vibrations of atoms are slowed down by irradiating them with laser light of the appropriate frequency to a temperature close to absolute zero. Time is calculated by measuring the frequency of radiation resulting from the transition of electrons between levels, and the frequency of these oscillations depends on the electrostatic forces between the electrons and the nucleus, as well as on the mass of the nucleus. Currently, the most common atomic clocks use atoms of cesium, rubidium, or hydrogen. Cesium-based atomic clocks are the most accurate in long-term use. Their error is less than one second per million years. Hydrogen atomic clocks are about ten times more accurate over shorter periods of time, up to a week.

Other time measuring instruments

Other measuring instruments include chronometers, which measure time with sufficient accuracy for use in navigation. With their help, the geographical position is determined based on the position of the stars and planets. Today, a chronometer is usually carried on ships as a backup. navigation device, and maritime experts know how to use it in navigation. However, global navigation satellite systems are used more often than chronometers and sextants.

UTC

Coordinated Universal Time (UTC) is used throughout the world as the universal time measurement system. It is based on the International Atomic Time (TAI) system, which uses the weighted average time of more than 200 atomic clocks around the world to calculate accurate time. Since 2012, TAI has been 35 seconds ahead of UTC because UTC, unlike TAI, uses the average solar day. Since a solar day is slightly longer than 24 hours, coordination seconds are added to UTC to coordinate UTC with a solar day. Sometimes these seconds of coordination cause various problems, especially in areas where computers are used. To prevent such problems from arising, some institutions, such as the server department at Google, use “leap smearing” instead of coordination seconds - lengthening a number of seconds by milliseconds so that the sum of these extensions is equal to one second.

UTC is based on atomic clocks, while Greenwich Mean Time (GMT) is based on length sunny day. GMT is less accurate because it depends on the Earth's rotation period, which is not constant. GMT was widely used in the past, but now UTC is used instead.

Calendars

Calendars consist of one or more levels of cycles such as days, weeks, months and years. They are divided into lunar, solar, lunisolar.

Lunar calendars

Lunar calendars are based on the phases of the moon. Each month is one lunar cycle, and the year is 12 months or 354.37 days. The lunar year is shorter than the solar year, and as a result, lunar calendars synchronize with the solar year only once every 33 lunar years. One of these calendars is Islamic. It is used for religious purposes and as the official calendar in Saudi Arabia.

Solar calendars

Solar calendars are based on the movement of the Sun and the seasons. Their frame of reference is the solar or tropical year, which is the time it takes for the Sun to complete one cycle of seasons, such as from winter solstice to winter solstice. A tropical year is 365,242 days. Because of the precession of the Earth's axis, that is, the slow change in the position of the Earth's axis of rotation, the tropical year is about 20 minutes shorter than the time it takes the Earth to orbit the Sun once relative to the fixed stars (the sidereal year). The tropical year gradually becomes shorter by 0.53 seconds every 100 tropical years, so reform will likely be needed in the future to synchronize solar calendars with the tropical year.

The most famous and widely used solar calendar is the Gregorian calendar. It is based on the Julian calendar, which in turn is based on the old Roman calendar. The Julian calendar assumes that a year consists of 365.25 days. In fact, the tropical year is 11 minutes shorter. As a result of this inaccuracy, by 1582 the Julian calendar was 10 days ahead of the tropical year. The Gregorian calendar was used to correct this discrepancy, and gradually it replaced other calendars in many countries. Some places, including the Orthodox Church, still use the Julian calendar. By 2013, the difference between the Julian and Gregorian calendars is 13 days.

To synchronize the 365-day Gregorian year with the 365.2425-day tropical year, the Gregorian calendar adds a leap year of 366 days. This is done every four years, except for years that are divisible by 100 but not divisible by 400. For example, 2000 was a leap year, but 1900 was not.

Lunar-solar calendars

Lunisolar calendars are a combination of lunar and solar calendars. Typically, their month is equal to the lunar phase, and the months alternate between 29 and 30 days, since the approximate average length of a lunar month is 29.53 days. To synchronize the lunisolar calendar with the tropical year, every few years to the year lunar calendar a thirteenth month is added. For example, in the Hebrew calendar, the thirteenth month is added seven times over the course of nineteen years - this is called the 19-year cycle, or the Metonic cycle. The Chinese and Hindu calendars are also examples of lunisolar calendars.

Other calendars

Other types of calendars are based on astronomical phenomena, such as the movement of Venus, or historical events, such as changes in rulers. For example, the Japanese calendar (年号 nengō, literally the name of an era) is used in addition to the Gregorian calendar. The name of the year corresponds to the name of the period, which is also called the emperor's motto, and the year of the reign of the emperor of that period. Upon accession to the throne, the new emperor approves his motto, and the countdown of a new period begins. The emperor's motto later becomes his posthumous name. According to this scheme, 2013 is called Heisei 25, that is, the 25th year of the reign of Emperor Akihito of the Heisei period.

Do you find it difficult to translate units of measurement from one language to another? Colleagues are ready to help you. Post a question in TCTerms and within a few minutes you will receive an answer.

The time calculator is designed to perform various time calculations and has several functions:

• indication of the user's current time,
• calculation of the time interval between two given points,
• converting time from one unit to another (seconds, minutes, hours, days, HH:MM:SS).

Time calculator will help you determine the remaining time at a given moment. For example, by setting the end time of the working day, you can find out exactly how long you have to work today. Or, for example, how much time is left for sleep. To do this, simply enter the time for which you set your alarm and the current time.

But, besides comical ways to use the time calculator, it can also be used for real purposes. Officials responsible for calculating the time worked by employees of the organization to determine overtime can also resort to a time calculator. To do this, it is enough to enter the employee’s arrival and departure time from work according to the electronic pass system, and the calculator itself will calculate the number of hours worked.

In addition, a time calculator can be useful for determining the recording time on video media. If several recordings have been made on video media, then by setting the start and end times of the recording, you can determine its duration.

In addition to the indicated ways of using the time interval calculation function, many more examples can be given, but we can say with confidence that everyone can find a use for it both for personal, perhaps entertainment, purposes, and for serious work issues.

Time calculator

Hours: Minutes: Seconds

Difference:

The time calculator's function for converting from one time unit to another allows you to easily convert days into hours, minutes and even seconds, into the hours-minutes-seconds format, and also in the opposite direction.

For example, you are going to the cinema to watch something from the latest releases, and when you go to a website with descriptions of films, you find out that the duration of the film is 164 minutes, which, you see, is not very clear. But, with the help of a time calculator, you can easily determine that the duration of the film is 2 hours 44 minutes, which is much clearer for planning your time.
