How to Convert hh:mm Digital Time to Decimal Hours

Employers typically use decimal hours to calculate work week pay. They take the number of hours worked in a week in decimal form, and multiply that by the rate of pay. If you worked 41:15, 41 hours and 15 minutes, how would you calculate your total pay?

You need to convert the hh:mm time of 41:15 to decimal hours.

Converting from Minutes to Decimal Hours

You worked 41 whole hours, so that will be the same in decimal hours. You only need to convert 15 minutes into decimal hours.

  1. Take your number of minutes and divide by 60. In this example your partial hour is 15 minutes:
    15/60 = 0.25
  2. Add your whole hours back in to get 41.25 hours. So 41 hours, 15 minutes equals 41.25 hours.
  3. Multiply your rate of pay by decimal hours to get your total pay before taxes.

In Reverse, Converting from Decimal Hours to Minutes

  1. Take your number of minutes and multiply by 60
  2. Say you had a decimal of 0.75 hours. Multiply:
    0.75 × 60 = 45 minutes
