Kilograms per Second to Grams per Second (kg/s to g/s)
1 kilogram per second (kg/s) = 1000 grams per second (g/s). 1 g/s = 0.001 kg/s. Example: 15 kg/s = 15 × 1000 = 15000 g/s.

How to Convert Kilogram per Second to Gram per Second
- 1 kg/s = 1000 g/s
- 1 g/s = 0.001 kg/s
- Example: convert 15 kg/s to g/s: 15 kg/s = 15 × 1000 g/s = 15000 g/s
Formula
g/s = kg/s × 1000
Derivation from SI units:
- Mass per unit time: kg/s.
- 1 g/s = 10⁻³ kg/s.
Both units are defined exactly, so the factor is exact. Kilogram per Second definition: kilogram per second; Gram per Second definition: gram per second.
Worked examples
- A reading of 1 kg/s converts to 1000 g/s.
1 kg/s × 1000 = 1000 g/s - A value of 10 kg/s is 10000 g/s.
10 kg/s × 1000 = 10000 g/s

Where it's used
Kilograms per Second are used for mass and energy balances, 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 second?
1 kg/s = 1000 g/s.
How do I convert kilograms per second to grams per second?
Multiply the value in kg/s by 1000. For example, 15 kg/s × 1000 = 15000 g/s.
Is the kg/s to g/s conversion exact?
Yes. Both units are defined exactly, and 1 kg/s is exactly 1000 g/s.
