How to Convert Pound per Minute to Kilogram per Hour
- 1 lb/min = 27.2155422 kg/h
- 1 kg/h = 0.03674371036 lb/min
- Example: convert 15 lb/min to kg/h: 15 lb/min = 15 × 27.2155422 kg/h = 408.233133 kg/h
Formula
kg/h = lb/min × 27.2155422
Derivation from SI units:
- 1 lb/min = 0.45359237/60 kg/s.
- 1 kg/h = 1/3600 kg/s.
- 1 lb/min = 0.007559872833333 kg/s ÷ 0.0002777777777778 kg/s per kg/h = 27.2155422 kg/h
Both units are defined exactly, so the factor is exact. Pound per Minute definition: pound per minute; Kilogram per Hour definition: kilogram per hour.
Worked examples
- A reading of 5 lb/min converts to 136.077711 kg/h.
5 lb/min × 27.2155422 = 136.077711 kg/h - A value of 50 lb/min is 1360.77711 kg/h.
50 lb/min × 27.2155422 = 1360.77711 kg/h
