Divide minutes by 60. For example, 15 minutes = 0.25 hours, 30 minutes = 0.50 hours, and 45 minutes = 0.75 hours. The table rounds displayed values to two decimal places.

Two-decimal values are convenient for entry and display. Keep the underlying minutes—or more decimal places—until the final calculation when precision matters.
02The exact conversion formula
Convert 7 hours 38 minutes
- 38 ÷ 600.6333…
- 7 + 0.6333…7.6333…
- Displayed to two decimals7.63 hours
03Decimal time is not clock notation
.30 of an hour is only 18 minutes.
30 minutes is one-half of 60 minutes.
04Conversion and rounding are different
Converting minutes to decimals changes the format without changing the amount of time. Time-clock rounding changes recorded punches according to a policy. Do the conversion exactly unless a valid rounding policy applies; see the separate guide to federal time-clock rounding rules.

Common questions
What is 20 minutes as a decimal?
20 ÷ 60 = 0.3333…, normally displayed as 0.33 hours.
Why does the chart show 0.67 for 40 minutes?
40 ÷ 60 = 0.6666…. The chart rounds that value to two decimal places.
Should I round each day before adding a week?
For ordinary mathematical conversion, add the exact minutes first and round the final displayed total. An employer's lawful timekeeping policy may specify a different procedure.
