Kilograms per Second to Tonnes per Hour (kg/s to t/h)
1 kilogram per second (kg/s) = 3.6 tonnes per hour (t/h). 1 t/h = 0.2777777778 kg/s. Example: 15 kg/s = 15 × 3.6 = 54 t/h.

How to Convert Kilogram per Second to Tonne per Hour
- 1 kg/s = 3.6 t/h
- 1 t/h = 0.2777777778 kg/s
- Example: convert 15 kg/s to t/h: 15 kg/s = 15 × 3.6 t/h = 54 t/h
Formula
t/h = kg/s × 3.6
Derivation from SI units:
- Mass per unit time: kg/s.
- 1 t/h = 1000/3600 kg/s ≈ 0.2778 kg/s.
Both units are defined exactly, so the factor is exact. Kilogram per Second definition: kilogram per second; Tonne per Hour definition: tonne per hour.
Worked examples
- A reading of 1 kg/s converts to 3.6 t/h.
1 kg/s × 3.6 = 3.6 t/h - A value of 10 kg/s is 36 t/h.
10 kg/s × 3.6 = 36 t/h

Where it's used
Kilograms per Second are used for mass and energy balances, while tonnes per hour appear in boiler capacity (TPH). Both measure mass flow rate ṁ, so the conversion is a fixed factor.

Frequently asked questions
How many tonnes per hour are in 1 kilogram per second?
1 kg/s = 3.6 t/h.
How do I convert kilograms per second to tonnes per hour?
Multiply the value in kg/s by 3.6. For example, 15 kg/s × 3.6 = 54 t/h.
Is the kg/s to t/h conversion exact?
Yes. Both units are defined exactly, and 1 kg/s is exactly 3.6 t/h.
