Convert Grams per Second to Kilograms per Hour (g/s to kg/h)
1 gram per second (g/s) = 3.6 kilograms per hour (kg/h). 1 kg/h = 0.2777777778 g/s. Example: 15 g/s = 15 × 3.6 = 54 kg/h.

How to Convert Gram per Second to Kilogram per Hour
- 1 g/s = 3.6 kg/h
- 1 kg/h = 0.2777777778 g/s
- Example: convert 15 g/s to kg/h: 15 g/s = 15 × 3.6 kg/h = 54 kg/h
Formula
kg/h = g/s × 3.6
Derivation from SI units:
- 1 g/s = 10⁻³ kg/s.
- 1 kg/h = 1/3600 kg/s.
- 1 g/s = 0.001 kg/s ÷ 0.0002777777777778 kg/s per kg/h = 3.6 kg/h
Both units are defined exactly, so the factor is exact. Gram per Second definition: gram per second; Kilogram per Hour definition: kilogram per hour.
Worked examples
- A reading of 2 g/s converts to 7.2 kg/h.
2 g/s × 3.6 = 7.2 kg/h - A value of 20 g/s is 72 kg/h.
20 g/s × 3.6 = 72 kg/h

Where it's used
Grams per Second are used for automotive MAF sensors, 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 gram per second?
1 g/s = 3.6 kg/h.
How do I convert grams per second to kilograms per hour?
Multiply the value in g/s by 3.6. For example, 15 g/s × 3.6 = 54 kg/h.
Is the g/s to kg/h conversion exact?
Yes. Both units are defined exactly, and 1 g/s is exactly 3.6 kg/h.
