Hour to Days and Hours Converter (and vice versa)

Converting decimal hours to days and hours

The conversion of decimal hours to days [d] and hours [h] is best explained with an example. Thirty decimal hours are used as the starting point for the calculation example. First, this value is divided by 24 to calculate the number of decimal days. The result of this calculation is 1.25 decimal days. The number to the left of the decimal point is the integer part, which in this example is 1. This number can be taken unchanged and corresponds to the final result of 1 day. The number to the right of the decimal point must still be converted into hours [h] by multiplying it by 24. 0.25 * 24 equals 6 hours [h]. In total, 30 decimal hours correspond to 1 day and 6 hours [h].

Converting days and hours to decimal hours

To convert days [d] and hours [h] to decimal hours, multiply the days [d] by 24 and add them to the hours [h].

• Decimal hours = (days [d] * 24 + hours [h])
