How to Convert Pound per Hour to Pound per Minute
- 1 lb/h = 0.01666666667 lb/min
- 1 lb/min = 60 lb/h
- Example: convert 15 lb/h to lb/min: 15 lb/h = 15 × 0.01666666667 lb/min = 0.25 lb/min
Formula
lb/min = lb/h × 0.01666666666667
or lb/min = lb/h ÷ 60
Derivation from SI units:
- 1 lb/h = 0.45359237/3600 kg/s.
- 1 lb/min = 0.45359237/60 kg/s.
- 1 lb/h = 0.0001259978805556 kg/s ÷ 0.007559872833333 kg/s per lb/min = 0.01666666666667 lb/min
Both units are defined exactly, so the factor is exact. Pound per Hour definition: pound per hour; Pound per Minute definition: pound per minute.
Worked examples
- A reading of 1000 lb/h converts to 16.66666667 lb/min.
1000 lb/h × 0.01666666667 = 16.66666667 lb/min - A value of 25000 lb/h is 416.6666667 lb/min.
25000 lb/h × 0.01666666667 = 416.6666667 lb/min
