How to Convert Hour to Minute
- 1 h = 60 min
- 1 min = 0.01666666667 h
- Example: convert 15 h to min: 15 h = 15 × 60 min = 900 min
Formula
min = h × 60
Derivation from SI units:
- 1 h = 60 min = 3600 s
- 1 min = 60 s
- 1 h = 3600 s ÷ 60 s per min = 60 min
Both units are defined exactly, so the factor is exact. Hour definition: hour; Minute definition: minute.
Worked examples
- A 1.5 h job takes 90 min.
1.5 h × 60 = 90 min - 0.75 h is 45 min.
0.75 h × 60 = 45 min
