How to Convert Pound per Minute to Tonne per Hour
- 1 lb/min = 0.0272155422 t/h
- 1 t/h = 36.74371036 lb/min
- Example: convert 15 lb/min to t/h: 15 lb/min = 15 × 0.0272155422 t/h = 0.408233133 t/h
Formula
t/h = lb/min × 0.0272155422
or t/h = lb/min ÷ 36.74371036415
Derivation from SI units:
- 1 lb/min = 0.45359237/60 kg/s.
- 1 t/h = 1000/3600 kg/s ≈ 0.2778 kg/s.
- 1 lb/min = 0.007559872833333 kg/s ÷ 0.2777777777778 kg/s per t/h = 0.0272155422 t/h
Both units are defined exactly, so the factor is exact. Pound per Minute definition: pound per minute; Tonne per Hour definition: tonne per hour.
Worked examples
- A reading of 5 lb/min converts to 0.136077711 t/h.
5 lb/min × 0.0272155422 = 0.136077711 t/h - A value of 50 lb/min is 1.36077711 t/h.
50 lb/min × 0.0272155422 = 1.36077711 t/h
