Convert Kilograms per Hour to Grams per Second (kg/h to g/s)
1 kilogram per hour (kg/h) = 0.2777777778 grams per second (g/s). 1 g/s = 3.6 kg/h. Example: 15 kg/h = 15 × 0.2777777778 = 4.166666667 g/s.

How to Convert Kilogram per Hour to Gram per Second
- 1 kg/h = 0.2777777778 g/s
- 1 g/s = 3.6 kg/h
- Example: convert 15 kg/h to g/s: 15 kg/h = 15 × 0.2777777778 g/s = 4.166666667 g/s
Formula
g/s = kg/h × 0.2777777777778
or g/s = kg/h ÷ 3.6
Derivation from SI units:
- 1 kg/h = 1/3600 kg/s.
- 1 g/s = 10⁻³ kg/s.
- 1 kg/h = 0.0002777777777778 kg/s ÷ 0.001 kg/s per g/s = 0.2777777777778 g/s
Both units are defined exactly, so the factor is exact. Kilogram per Hour definition: kilogram per hour; Gram per Second definition: gram per second.
Worked examples
- A reading of 100 kg/h converts to 27.77777778 g/s.
100 kg/h × 0.2777777778 = 27.77777778 g/s - A value of 1000 kg/h is 277.7777778 g/s.
1000 kg/h × 0.2777777778 = 277.7777778 g/s

Where it's used
Kilograms per Hour are used for boiler steam rating (kg/h), while grams per second appear in automotive MAF sensors. Both measure mass flow rate ṁ, so the conversion is a fixed factor.

Frequently asked questions
How many grams per second are in 1 kilogram per hour?
1 kg/h = 0.2777777778 g/s.
How do I convert kilograms per hour to grams per second?
Multiply the value in kg/h by 0.2777777778, or divide it by 3.6. For example, 15 kg/h × 0.2777777778 = 4.166666667 g/s.
Is the kg/h to g/s conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
