Kilograms per Second to Kilograms per Hour (kg/s to kg/h)
1 kilogram per second (kg/s) = 3600 kilograms per hour (kg/h). 1 kg/h = 0.0002777777778 kg/s. Example: 2.5 kg/s = 2.5 × 3600 = 9000 kg/h.

How to Convert Kilogram per Second to Kilogram per Hour
- 1 kg/s = 3600 kg/h
- 1 kg/h = 0.0002777777778 kg/s
- Example: convert 2.5 kg/s to kg/h: 2.5 kg/s = 2.5 × 3600 kg/h = 9000 kg/h
Formula
kg/h = kg/s × 3600
Derivation from SI units:
- Mass per unit time: kg/s.
- 1 kg/h = 1/3600 kg/s.
Both units are defined exactly, so the factor is exact. Kilogram per Second definition: kilogram per second; Kilogram per Hour definition: kilogram per hour.
Worked examples
- 1 kg/s is 3600 kg/h.
1 kg/s × 3600 = 3600 kg/h - A flow of 2.5 kg/s is 9000 kg/h.
2.5 kg/s × 3600 = 9000 kg/h
