Additionally, it means that there are four periods of 60 minutes, one period of 10 minutes and 10 seconds. Whenever you see this format “hh:mm” or extended “hh:mm:ss”, it indicates that the time is expressed in the standard 24-hour time system.Įxample: 4:10:15 – we read as “four hours, ten minutes and fifteen seconds”. For instance, there are 1,440 minutes in a day, and 1 hour in seconds is equal to 3600. In the 24-hour system, we express hours as 60 minutes and minute as 60 seconds. What does 24-hour standard time look like? Our todays’ way of measuring and expressing time originates from the old Egyptian time. They used a sexagesimal system, with a base of 60, which was afterwards accepted and used by Babylonians.Īdditionally, Babylonians divided both the circle and the year into 360 segments. ![]() Interestingly, Egyptians were the first people who used a 24-hour system, and they divided a day into 24 equal parts. We learned about the decimal time system and its origins, but what about the 24-hour time system? What are its origins? ![]() Therefore, there are zero chances that the decimal system may come into use and become a part of everyday life. Today, standardised systems are used everywhere, including time. In 1795 when a standardised system was introduced, which was way more useful and effective, these localised weights and measures, decimals system pretty much was already dead. However, it’s important to mention that the old time system failed to become popular and spread its usage worldwide. In the 1790s in France, after the introduction of metric weights and measures, people divided a day into 10 hours, where each hour equalled 100 minutes and each minute was equivalent to 100 seconds. When did it all start, and at what period in history decimal time system was used? Again, it is straightforward: 3 hrs = 300 minutes or 30,000 seconds. Or, for example, when you want to convert 3 hours in minutes and seconds. Why? Because it’s easier to interpret it and perform conversions if the time is expressed in decimals.įor instance, let’s assume you want to interpret 1:25:30 (hh:mm:ss) as a time in decimal form. Therefore, one day in UTC standard format is equal to 86400 seconds.Ĭonsidering which time system is simpler and easier for conversion and calculations, the winner is a decimal format system. Each hour equals 60 minutes, and each minute is made of 60 seconds. In opposition, a standard UTC works by dividing the day into 24 hours. Therefore, one day was equivalent to 100000 decimal seconds. In addition, each decimal hour consisted of 100 decimal minutes and each minute was made of 100 decimal seconds. The system at that period worked by dividing the day into 10 decimal hours. It often refers to the system of time, which was most popular in France in 1792 during the French Revolution. It represents the time of day using decimal units. Would you like to explore more of our calculators related to time, times zones, drive times or times conversions? Take a look at the list below of some calculators we recommend you to check out: It is a very handy and easy-to-use tool that instantly converts any time into its decimal equivalent. ![]() For instance, if you want to convert 2:30 pm to military time, you should add 12 to the hour portion, resulting in 14:30 hours.Whether you want to know the equivalent of time expressed in hh:mm:ss in its decimal form, or do some math, such as adding or subtracting hours, minutes, or seconds – you will eagerly look for a tool like our Time to Decimal Calculator. If the time is in the PM, instead of subtracting 12 hours from the hour portion of the time, you should add 12 to the hour portion of the time. Again, the exception is 12:00 AM, which is displayed as 00:00 in military time. If the time is in the AM, you should remove the “AM” portion and add a leading zero to any single-digit hours (e.g., 08:00 for 8:00 AM). The exception is 12:00 AM, which is displayed as 00:00 in the 24-hour time format How To Manually Convert a 12-Hour Format to Military TimeĬonverting regular time to military time is also a simple process. For example, 8:30 hours (military time) is equal to 8:30 AM in regular time. In most cases, if the military time is less than or equal to 12:00 PM, then you can simply add "AM" to the end of the time. So, 16:30 hours becomes 4:30 PM in regular time. Since 16 is greater than 12, you need to subtract 12 from 16, which gives you 4. To convert military time to regular time, you just need to subtract 12 from any time that's greater than 12:00 PM.įor example, let's say you want to convert 16:30 hours (military time) to regular time. ![]() How To Manually Convert Military Time (24-Hour) to 12-Hour Standard TimeĬonverting military time to regular time can seem complicated, but it's actually quite simple.
