How to Convert Kilogram per Second to Pound per Second
- 1 kg/s = 2.204622622 lb/s
- 1 lb/s = 0.45359237 kg/s
- Example: convert 15 kg/s to lb/s: 15 kg/s = 15 × 2.204622622 lb/s = 33.06933933 lb/s
Formula
lb/s = kg/s × 2.204622621849
Derivation from SI units:
- Mass per unit time: kg/s.
- 1 lb/s = 0.45359237 kg/s.
Both units are defined exactly, so the factor is exact. Kilogram per Second definition: kilogram per second; Pound per Second definition: pound per second.
Worked examples
- A reading of 1 kg/s converts to 2.204622622 lb/s.
1 kg/s × 2.204622622 = 2.204622622 lb/s - A value of 10 kg/s is 22.04622622 lb/s.
10 kg/s × 2.204622622 = 22.04622622 lb/s
