How to Convert Gram/Second to Kilogram/Second

To convert from Gram/Second (g/s) to Kilogram/Second (kg/s), multiply the value by 0.001.

Formula: kg/s = g/s × 0.001

Reverse: g/s = kg/s × 1,000

Step-by-Step Example

Start with your value in Gram/Second. For example: 5 g/s
Multiply by the conversion factor: 5 x 0.001
The result is: 0.005 kg/s

About Gram/Second

The gram/second (g/s) is a unit of mass flow rate. One gram/second equals 0.001 base units. UnitConvertLab converts it against every other mass flow rate unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: mass flow rate calculations, engineering and science, education.

About Kilogram/Second

The kilogram/second (kg/s) is a unit of mass flow rate. One kilogram/second equals 1 base unit. UnitConvertLab converts it against every other mass flow rate unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: mass flow rate calculations, engineering and science, education.
