Grams per Second to Kilograms per Second (g/s to kg/s)
1 gram per second (g/s) = 0.001 kilograms per second (kg/s). 1 kg/s = 1000 g/s. Example: 15 g/s = 15 × 0.001 = 0.015 kg/s.

How to Convert Gram per Second to Kilogram per Second
- 1 g/s = 0.001 kg/s
- 1 kg/s = 1000 g/s
- Example: convert 15 g/s to kg/s: 15 g/s = 15 × 0.001 kg/s = 0.015 kg/s
Formula
kg/s = g/s ÷ 1000
Derivation from SI units:
- 1 g/s = 10⁻³ kg/s.
- Mass per unit time: kg/s.
Both units are defined exactly, so the factor is exact. Gram per Second definition: gram per second; Kilogram per Second definition: kilogram per second.
Worked examples
- A reading of 2 g/s converts to 0.002 kg/s.
2 g/s × 0.001 = 0.002 kg/s - A value of 20 g/s is 0.02 kg/s.
20 g/s × 0.001 = 0.02 kg/s

Where it's used
Grams per Second are used for automotive MAF sensors, while kilograms per second appear in mass and energy balances. Both measure mass flow rate ṁ, so the conversion is a fixed factor.

Frequently asked questions
How many kilograms per second are in 1 gram per second?
1 g/s = 0.001 kg/s.
How do I convert grams per second to kilograms per second?
Multiply the value in g/s by 0.001, or divide it by 1000. For example, 15 g/s × 0.001 = 0.015 kg/s.
Is the g/s to kg/s conversion exact?
Yes. Both units are defined exactly, and 1 g/s is exactly 0.001 kg/s.
