Because an hour includes 60 minutes (and not one hundred minutes) adding time takes a bit of time.

Hours and minutes are two different units that measure time. However, minutes are not a decimal number of hours, i.e. half an hour (0.5 of an hour) is not 50 minutes, it’s 30 minutes… making time calculation a brain teaser.

How to add time?

  • Step one - convert the minutes to decimals - divide the minutes by 60
  • Step two - Add your results with a conventional calculator
  • Example: 6:45 - divide the minutes 45/60=0.75 - equlas 6.75
  • Example: 2:24 - divide the minutes 24/60=0.40 - equals 2.40
  • Use the calculator to add 6.75 + 2.40 = 9.15
  • Your total is 9.15 hours or 9:09 (0.15*60= 9 min)

To add time with a conventional calculator requires you to first convert your minutes into a decimal number, by dividing the minutes into 60. Our calculator for time adds your hours and minutes in no time. Print or email your Time Calculation for your records, and to double check for accuracy.
