Tonnes per Hour to Kilograms per Second (t/h to kg/s)
1 tonne per hour (t/h) = 0.2777777778 kilograms per second (kg/s). 1 kg/s = 3.6 t/h. Example: 10 t/h = 10 × 0.2777777778 = 2.777777778 kg/s.
Also searched as TPH to kg/s, t/h to kg/sec and tonnes per hour to kilograms per second.

How to Convert Tonne per Hour to Kilogram per Second
- 1 t/h = 0.2777777778 kg/s
- 1 kg/s = 3.6 t/h
- Example: convert 10 t/h to kg/s: 10 t/h = 10 × 0.2777777778 kg/s = 2.777777778 kg/s
Formula
kg/s = t/h × 0.2777777777778
or kg/s = t/h ÷ 3.6
Derivation from SI units:
- 1 t/h = 1000/3600 kg/s ≈ 0.2778 kg/s.
- Mass per unit time: kg/s.
Both units are defined exactly, so the factor is exact. Tonne per Hour definition: tonne per hour; Kilogram per Second definition: kilogram per second.
Worked examples
- A boiler rated 10 t/h makes 2.777777778 kg/s of steam.
10 t/h × 0.2777777778 = 2.777777778 kg/s - A conveyor at 100 t/h carries 27.77777778 kg/s.
100 t/h × 0.2777777778 = 27.77777778 kg/s

Frequently asked questions
How many kg/s is 1 TPH?
1 t/h = 0.2777777778 kg/s.
How many kilograms per second are in 1 tonne per hour?
1 t/h = 0.2777777778 kg/s.
How do I convert tonnes per hour to kilograms per second?
Multiply the value in t/h by 0.2777777778, or divide it by 3.6. For example, 10 t/h × 0.2777777778 = 2.777777778 kg/s.
Is the t/h to kg/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).
