How to Convert Pound per Second to Pound per Minute
- 1 lb/s = 60 lb/min
- 1 lb/min = 0.01666666667 lb/s
- Example: convert 15 lb/s to lb/min: 15 lb/s = 15 × 60 lb/min = 900 lb/min
Formula
lb/min = lb/s × 60
Derivation from SI units:
- 1 lb/s = 0.45359237 kg/s.
- 1 lb/min = 0.45359237/60 kg/s.
- 1 lb/s = 0.45359237 kg/s ÷ 0.007559872833333 kg/s per lb/min = 60 lb/min
Both units are defined exactly, so the factor is exact. Pound per Second definition: pound per second; Pound per Minute definition: pound per minute.
Worked examples
- A reading of 10 lb/s converts to 600 lb/min.
10 lb/s × 60 = 600 lb/min - A value of 200 lb/s is 12000 lb/min.
200 lb/s × 60 = 12000 lb/min
