Pounds per Minute to Kilograms per Second (lb/min to kg/s)
1 pound per minute (lb/min) = 0.007559872833 kilograms per second (kg/s). 1 kg/s = 132.2773573 lb/min. Example: 15 lb/min = 15 × 0.007559872833 = 0.1133980925 kg/s.

How to Convert Pound per Minute to Kilogram per Second
- 1 lb/min = 0.007559872833 kg/s
- 1 kg/s = 132.2773573 lb/min
- Example: convert 15 lb/min to kg/s: 15 lb/min = 15 × 0.007559872833 kg/s = 0.1133980925 kg/s
Formula
kg/s = lb/min × 0.007559872833333
or kg/s = lb/min ÷ 132.2773573109
Derivation from SI units:
- 1 lb/min = 0.45359237/60 kg/s.
- Mass per unit time: kg/s.
Both units are defined exactly, so the factor is exact. Pound per Minute definition: pound per minute; Kilogram per Second definition: kilogram per second.
Worked examples
- A reading of 5 lb/min converts to 0.03779936417 kg/s.
5 lb/min × 0.007559872833 = 0.03779936417 kg/s - A value of 50 lb/min is 0.3779936417 kg/s.
50 lb/min × 0.007559872833 = 0.3779936417 kg/s
