How to Convert Kilogram per Hour to Pound per Second
- 1 kg/h = 0.0006123951727 lb/s
- 1 lb/s = 1632.932532 kg/h
- Example: convert 15 kg/h to lb/s: 15 kg/h = 15 × 0.0006123951727 lb/s = 0.009185927591 lb/s
Formula
lb/s = kg/h × 0.0006123951727358
or lb/s = kg/h ÷ 1632.932532
Derivation from SI units:
- 1 kg/h = 1/3600 kg/s.
- 1 lb/s = 0.45359237 kg/s.
- 1 kg/h = 0.0002777777777778 kg/s ÷ 0.45359237 kg/s per lb/s = 0.0006123951727358 lb/s
Both units are defined exactly, so the factor is exact. Kilogram per Hour definition: kilogram per hour; Pound per Second definition: pound per second.
Worked examples
- A reading of 100 kg/h converts to 0.06123951727 lb/s.
100 kg/h × 0.0006123951727 = 0.06123951727 lb/s - A value of 1000 kg/h is 0.6123951727 lb/s.
1000 kg/h × 0.0006123951727 = 0.6123951727 lb/s
