Convert Kilograms per Hour to Tonnes per Hour (kg/h to t/h)
1 kilogram per hour (kg/h) = 0.001 tonnes per hour (t/h). 1 t/h = 1000 kg/h. Example: 15 kg/h = 15 × 0.001 = 0.015 t/h.

How to Convert Kilogram per Hour to Tonne per Hour
- 1 kg/h = 0.001 t/h
- 1 t/h = 1000 kg/h
- Example: convert 15 kg/h to t/h: 15 kg/h = 15 × 0.001 t/h = 0.015 t/h
Formula
t/h = kg/h ÷ 1000
Derivation from SI units:
- 1 kg/h = 1/3600 kg/s.
- 1 t/h = 1000/3600 kg/s ≈ 0.2778 kg/s.
- 1 kg/h = 0.0002777777777778 kg/s ÷ 0.2777777777778 kg/s per t/h = 0.001 t/h
Both units are defined exactly, so the factor is exact. Kilogram per Hour definition: kilogram per hour; Tonne per Hour definition: tonne per hour.
Worked examples
- A reading of 100 kg/h converts to 0.1 t/h.
100 kg/h × 0.001 = 0.1 t/h - A value of 1000 kg/h is 1 t/h.
1000 kg/h × 0.001 = 1 t/h

Where it's used
Kilograms per Hour are used for boiler steam rating (kg/h), 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 hour?
1 kg/h = 0.001 t/h.
How do I convert kilograms per hour to tonnes per hour?
Multiply the value in kg/h by 0.001, or divide it by 1000. For example, 15 kg/h × 0.001 = 0.015 t/h.
Is the kg/h to t/h conversion exact?
Yes. Both units are defined exactly, and 1 kg/h is exactly 0.001 t/h.
