How it works

  1. Type the value. Decimal (7.5), clock time (7:30 or 8h15), or minutes only (90min).
  2. See the other forms. A decimal highlights hh:mm. A clock time highlights the decimal. Total minutes and the hours-plus-minutes split sit beside them.
  3. Use the table. 0.25 is 15 minutes, 0.50 is 30, and 0.10 is 6. Enter an hourly rate to see what that time is worth.

Frequently asked questions

How do I convert decimal hours to hours and minutes?

Multiply the decimal part by 60. 7.5 is 7 hours and 0.5 × 60 = 30 minutes, so 7:30. 8.25 becomes 8:15 and 0.1 becomes 0:06.

How do I convert hours and minutes to a decimal?

Divide the minutes by 60 and add them to the hours. 7:30 becomes 7.50 h, 8:15 becomes 8.25 h, and 7:20 becomes 7.33 h.

Is 7.50 the same as 7:50?

7.50 in decimal hours is 7 hours and a half, or 7:30. 7:50 on a clock is different: 7 hours and 50 minutes, which is 7.83 h in decimal.

How do I convert minutes only?

Type 90min or 45min. 90 minutes become 1:30, or 1.50 h. A bare number such as 90 counts as hours, not minutes.

How is this different from the Hours Sum?

The converter changes a single value. The Hours Sum adds several durations. The Work Hours Calculator starts from clock-in, clock-out, and breaks.
