![]() ![]() Note that our Time to Decimal Calculator rounds the result as follows. Where hrs, min, and sec are hours, minutes, and seconds in standard 24-hour clock time format respectively (in HH:MM:SS time format).įor example, let’s convert the time 02:30:45 first to hours, then to minutes, and finally to seconds:ĭecimal hours = 2 + (30 / 60) + (45 / 3600) = 2 + 0.5 + 0.0125 = 2.5125, For example, a time of 1 hour 15 minutes can be represented as 1.25 hours, or 75 minutes, or 4500 seconds.įormulas for calculating time in decimal format have an obvious form and are shown below: In this case, it is first necessary to choose a convenient unit of time measurement (hours, minutes, or seconds). Therefore, to avoid unnecessary conversions when calculating, it is convenient to express time in the format of a decimal number. For example, adding two time intervals of 45 minutes and 30 minutes, we get as a result 75 minutes, which in the traditional representation of time means 1 hour and 15 minutes. Therefore, when performing mathematical operations with time, this must be taken into account. Indeed, as you know, 1 hour consists of 60 minutes, and 1 minute consists of 60 seconds. ![]() Calculations usually require the time interval to be expressed in decimal form. ![]() We are all used to this representation of time, but this format is not suitable for mathematical operations with time. Time is traditionally expressed in hours, minutes, and seconds. ![]()
