Minutes to decimal hours
Divide minutes by 60 to express them as a fraction of an hour. For an elapsed duration of 7 hours 45 minutes, that gives 7 + 45 ÷ 60 = 7.75 hours.

Find the minutes part of your duration below, then add the whole hours. The 60-minute row equals one full hour. Both decimal columns are rounded displays of the same calculation.

The formula, with worked examples
Decimal hours = whole hours + (remaining minutes ÷ 60). If you have a total number of minutes instead, divide that total by 60 once. The units are still hours; the decimal point does not separate hours from minutes.
For 18 minutes: 18 ÷ 60 = 0.30 hours (0.300 to three decimals). For 2 hours 18 minutes: 2 + 0.30 = 2.30 hours. A 138-minute duration gives the same result: 138 ÷ 60 = 2.30.
For 1 hour 8 minutes: 1 + 8 ÷ 60 = 1.1333… hours. Display that as 1.13 or 1.133 hours, while retaining the original 68 minutes for any later calculation.
Why 7:45 is 7.75 hours, not 7.45
When 7:45 describes a duration in hours:minutes, the 45 means 45 out of 60 minutes, or three quarters of an hour. Three quarters is 0.75, so the duration is 7.75 decimal hours. A clock reading of 7:45 is a time of day; you need a start and end time to find a duration.
By contrast, the fractional part of 7.45 decimal hours is 0.45 of an hour. Multiply it by 60: 0.45 × 60 = 27 minutes. That means 7 hours 27 minutes, which is 18 minutes shorter than 7 hours 45 minutes.
Keep the minutes; round the display
Some fractions of an hour never end in decimal form. One minute is 0.016666… hours. Two decimals show 0.02; three show 0.017. More displayed digits reduce the display error, but neither is an exact replacement for one minute.
For three separate one-minute intervals, adding the two-decimal displays gives 0.02 + 0.02 + 0.02 = 0.06 hours. Add the minutes first instead: 3 ÷ 60 = 0.05 hours. Taskono’s time calculators keep integer-minute totals and format the decimal result afterward. Adding already-rounded rows can disagree with the displayed total.
Rounding a display is different from rounding a work punch. Moving a recorded start from 9:02 to 9:00 changes the input time; showing 8 minutes as 0.13 hours only changes its representation. This chart neither changes punches nor chooses a rounding interval. Follow the time-entry rules that apply to your workplace; a conversion chart alone does not establish them.

Have clock-in times, clock-out times or breaks? Use a calculator to find elapsed minutes before converting them.
Sources and verification
The North Carolina Department of Labor publishes a minutes-to-decimal-hours reference. Our two-decimal column agrees with its values for 1–60 minutes. Taskono generates every row by dividing minutes by 60, including zero and the three-decimal column, and checks those calculations in automated tests.
