Convert Tonnes per Hour to Pounds per Second (t/h to lb/s)
1 tonne per hour (t/h) = 0.6123951727 pounds per second (lb/s). 1 lb/s = 1.632932532 t/h. Example: 15 t/h = 15 × 0.6123951727 = 9.185927591 lb/s.

How to Convert Tonne per Hour to Pound per Second
- 1 t/h = 0.6123951727 lb/s
- 1 lb/s = 1.632932532 t/h
- Example: convert 15 t/h to lb/s: 15 t/h = 15 × 0.6123951727 lb/s = 9.185927591 lb/s
Formula
lb/s = t/h × 0.6123951727358
or lb/s = t/h ÷ 1.632932532
Derivation from SI units:
- 1 t/h = 1000/3600 kg/s ≈ 0.2778 kg/s.
- 1 lb/s = 0.45359237 kg/s.
- 1 t/h = 0.2777777777778 kg/s ÷ 0.45359237 kg/s per lb/s = 0.6123951727358 lb/s
Both units are defined exactly, so the factor is exact. Tonne per Hour definition: tonne per hour; Pound per Second definition: pound per second.
Worked examples
- A reading of 10 t/h converts to 6.123951727 lb/s.
10 t/h × 0.6123951727 = 6.123951727 lb/s - A value of 100 t/h is 61.23951727 lb/s.
100 t/h × 0.6123951727 = 61.23951727 lb/s

Frequently asked questions
How many pounds per second are in 1 tonne per hour?
1 t/h = 0.6123951727 lb/s.
How do I convert tonnes per hour to pounds per second?
Multiply the value in t/h by 0.6123951727, or divide it by 1.632932532. For example, 15 t/h × 0.6123951727 = 9.185927591 lb/s.
Is the t/h to lb/s conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
