Pounds per Minute to Pounds per Second (lb/min to lb/s)
1 pound per minute (lb/min) = 0.01666666667 pounds per second (lb/s). 1 lb/s = 60 lb/min. Example: 15 lb/min = 15 × 0.01666666667 = 0.25 lb/s.

How to Convert Pound per Minute to Pound per Second
- 1 lb/min = 0.01666666667 lb/s
- 1 lb/s = 60 lb/min
- Example: convert 15 lb/min to lb/s: 15 lb/min = 15 × 0.01666666667 lb/s = 0.25 lb/s
Formula
lb/s = lb/min ÷ 60
Derivation from SI units:
- 1 lb/min = 0.45359237/60 kg/s.
- 1 lb/s = 0.45359237 kg/s.
- 1 lb/min = 0.007559872833333 kg/s ÷ 0.45359237 kg/s per lb/s = 0.01666666666667 lb/s
Both units are defined exactly, so the factor is exact. Pound per Minute definition: pound per minute; Pound per Second definition: pound per second.
Worked examples
- A reading of 5 lb/min converts to 0.08333333333 lb/s.
5 lb/min × 0.01666666667 = 0.08333333333 lb/s - A value of 50 lb/min is 0.8333333333 lb/s.
50 lb/min × 0.01666666667 = 0.8333333333 lb/s
