Time Duration Calculator

Convert hours and minutes to decimal hours

Divide minutes by 60, then add the whole hours. Decimal minutes are fractions of an hour, not base-100 minutes.

Step by step

  1. Keep the whole hours.
  2. Divide minutes by 60.
  3. Add the values.
  4. Round only when a required policy specifies an increment.

Worked example

7 hours 45 minutes = 7 + 45 ÷ 60 = 7.75 hours.

Common questions

Should I use 12-hour or 24-hour time?

Either works when written consistently. A 24-hour clock makes day-boundary arithmetic easier.

When should I round?

Keep the exact value unless the task or applicable policy tells you to round.
