Converting years to days and hours

The conversion of years [yr] to days [d] and hours [h] is best explained with an example. We will use 1.5 years [yr] as the starting point for our calculation example. First, this value is multiplied by 365.25 to calculate the number of decimal days. The result of this calculation is 547.875 decimal days. The number to the left of the decimal point is the integer part, which in this example is 547. This number can be taken unchanged and corresponds to the final result of 547 days [d]. The number to the right of the decimal point must still be converted into hours [h] by multiplying it by 24. 0.875 * 24 equals 21 hours [h]. In total, 1.5 years [yr] correspond to 547 days [d] and 21 hours [h].


Converting days and hours to years

To convert days [d] and hours [h] into years [yr], multiply the days [d] by 24 and add them to the hours [h]. The result of this calculation must then be divided by 8,766.

  • Years [yr] = (days [d] * 24 + hours [h]) ÷ 8,766
