![]() Therefore, it becomes simpler to interpret a timestamp and to perform conversions. The main advantage of a decimal time system is that, since the base used to divide the time is the same as the one used to represent it, the representation of hours, minutes and seconds can be handled as a unified value. This term is often used specifically to refer to the French Republican calendar time system used in France from 1794 to 1800, during the French Revolution, which divided the day into 10 decimal hours, each decimal hour into 100 decimal minutes and each decimal minute into 100 decimal seconds ( 100 000 decimal seconds per day), as opposed to the more familiar standard time, which divides the day into 24 hours, each hour into 60 minutes and each minute into 60 seconds ( 86 400 SI seconds per day). ![]() The large dial shows the ten hours of the decimal day in Arabic numerals, while the small dial shows the two 12-hour periods of the standard 24-hour day in Roman numerals.ĭecimal time is the representation of the time of day using units which are decimally related. At 22:03:05 UTC 22 February 2024 ( update)įrench decimal clock from the time of the French Revolution. Alternatively, just multiply 2.5 by 60 to get 150 minutes.Not to be confused with Metric time. 2.5 hours would equal 150 minutes since two hours times sixty equals 120 minutes, and 0.5 hours is 0.5 times sixty which is 30. In this case, perform the conversion of decimal to time as usual, then simply multiple the number of hours by sixty and add any remaining minutes to the number. Oftentimes one wants to convert decimal time to minutes instead of hours and minutes. Subtract 15 from 135, then divide the result by 60 to get the number of hours. 135 modulo 60 will give us the number of minutes, in this case that is 15. Finding the modulo of two numbers means to find the remainder of a division. Since zero times anything is zero, the answer is simply eight hours.Įxample 3: 135 minutes is how many hours and minutes? To calculate the number of hours and minutes, the modulo mathematical operation needs to be used. Then multiply 0.00 by 60 to get the number of minutes. ![]() Solution: as above, write down 8 as the number of hours. So 5.50 in decimal equals 5 hours 30 minutes.Įxample 2: convert 8.00 decimal hours to time. Then multiply 0.50 by 60, which is the same as dividing it by two in this case, to get the number of minutes. Solution: write down 5 as the number of hours. Then multiply the fractional part by sixty to get the number of minutes.Įxample 1: convert 5.50 decimal hours to time. To convert decimal hours to time first write down the whole part of the decimal number down - this is the number of whole hours. Alternatively, if the decimal time is in minutes, enter the number of minutes, for example 125, to see it converted to hours and minutes: 2 hours and 5 minutes in this example. It is common for payroll hours to be expressed as a decimal, whereas sometimes you need to know how many hours and minutes that represents.įor example, enter 7.25 in decimal and the output will be 7 hours and 15 minutes. To use the tool, simply enter the decimal time and it will be converted to hours and minutes below.
