How to Convert Pound per Second to Kilogram per Hour
- 1 lb/s = 1632.932532 kg/h
- 1 kg/h = 0.0006123951727 lb/s
- Example: convert 15 lb/s to kg/h: 15 lb/s = 15 × 1632.932532 kg/h = 24493.98798 kg/h
Formula
kg/h = lb/s × 1632.932532
Derivation from SI units:
- 1 lb/s = 0.45359237 kg/s.
- 1 kg/h = 1/3600 kg/s.
- 1 lb/s = 0.45359237 kg/s ÷ 0.0002777777777778 kg/s per kg/h = 1632.932532 kg/h
Both units are defined exactly, so the factor is exact. Pound per Second definition: pound per second; Kilogram per Hour definition: kilogram per hour.
Worked examples
- A reading of 10 lb/s converts to 16329.32532 kg/h.
10 lb/s × 1632.932532 = 16329.32532 kg/h - A value of 200 lb/s is 326586.5064 kg/h.
200 lb/s × 1632.932532 = 326586.5064 kg/h
