Convert in either direction — both sides work independently.
Hours and minutes → decimal
h
m
Decimal → hours and minutes
e.g. 7.75 for seven and three-quarter hours
Quick reference
Minutes are sixtieths, not hundredths — which is why 0:15 is 0.25 rather than 0.15.
| Hours and minutes | Decimal hours |
|---|---|
| 0:15 | 0.25 |
| 0:20 | 0.33 |
| 0:30 | 0.5 |
| 0:45 | 0.75 |
| 1:10 | 1.17 |
| 7:30 | 7.5 |
Starting from a clock-in and clock-out time instead? Use Hours Between Two Times. Nothing is uploaded anywhere — this runs entirely on your device.
