Convert Tonnes per Hour to Kilograms per Hour (t/h to kg/h)
1 tonne per hour (t/h) = 1000 kilograms per hour (kg/h). 1 kg/h = 0.001 t/h. Example: 15 t/h = 15 × 1000 = 15000 kg/h.

How to Convert Tonne per Hour to Kilogram per Hour
- 1 t/h = 1000 kg/h
- 1 kg/h = 0.001 t/h
- Example: convert 15 t/h to kg/h: 15 t/h = 15 × 1000 kg/h = 15000 kg/h
Formula
kg/h = t/h × 1000
Derivation from SI units:
- 1 t/h = 1000/3600 kg/s ≈ 0.2778 kg/s.
- 1 kg/h = 1/3600 kg/s.
- 1 t/h = 0.2777777777778 kg/s ÷ 0.0002777777777778 kg/s per kg/h = 1000 kg/h
Both units are defined exactly, so the factor is exact. Tonne per Hour definition: tonne per hour; Kilogram per Hour definition: kilogram per hour.
Worked examples
- A reading of 10 t/h converts to 10000 kg/h.
10 t/h × 1000 = 10000 kg/h - A value of 100 t/h is 100000 kg/h.
100 t/h × 1000 = 100000 kg/h

Where it's used
Tonnes per Hour are used for boiler capacity (TPH), while kilograms per hour appear in boiler steam rating (kg/h). Both measure mass flow rate ṁ, so the conversion is a fixed factor.

Frequently asked questions
How many kilograms per hour are in 1 tonne per hour?
1 t/h = 1000 kg/h.
How do I convert tonnes per hour to kilograms per hour?
Multiply the value in t/h by 1000. For example, 15 t/h × 1000 = 15000 kg/h.
Is the t/h to kg/h conversion exact?
Yes. Both units are defined exactly, and 1 t/h is exactly 1000 kg/h.
