How to Convert Pound per Hour to Tonne per Day
- 1 lb/h = 0.01088621688 t/day
- 1 t/day = 91.85927591 lb/h
- Example: convert 15 lb/h to t/day: 15 lb/h = 15 × 0.01088621688 t/day = 0.1632932532 t/day
Formula
t/day = lb/h × 0.01088621688
or t/day = lb/h ÷ 91.85927591037
Derivation from SI units:
- 1 lb/h = 0.45359237/3600 kg/s.
- 1 t/day = 1000/86,400 kg/s.
- 1 lb/h = 0.0001259978805556 kg/s ÷ 0.01157407407407 kg/s per t/day = 0.01088621688 t/day
Both units are defined exactly, so the factor is exact. Pound per Hour definition: pound per hour; Tonne per Day definition: tonne per day.
Worked examples
- A reading of 1000 lb/h converts to 10.88621688 t/day.
1000 lb/h × 0.01088621688 = 10.88621688 t/day - A value of 25000 lb/h is 272.155422 t/day.
25000 lb/h × 0.01088621688 = 272.155422 t/day
