How to Convert Tonne per Day to Pound per Minute
- 1 t/day = 1.530987932 lb/min
- 1 lb/min = 0.6531730128 t/day
- Example: convert 15 t/day to lb/min: 15 t/day = 15 × 1.530987932 lb/min = 22.96481898 lb/min
Formula
lb/min = t/day × 1.530987931839
Derivation from SI units:
- 1 t/day = 1000/86,400 kg/s.
- 1 lb/min = 0.45359237/60 kg/s.
- 1 t/day = 0.01157407407407 kg/s ÷ 0.007559872833333 kg/s per lb/min = 1.530987931839 lb/min
Both units are defined exactly, so the factor is exact. Tonne per Day definition: tonne per day; Pound per Minute definition: pound per minute.
Worked examples
- A reading of 100 t/day converts to 153.0987932 lb/min.
100 t/day × 1.530987932 = 153.0987932 lb/min - A value of 1000 t/day is 1530.987932 lb/min.
1000 t/day × 1.530987932 = 1530.987932 lb/min
