Mass Flow Rate

g/stokg/s

Convert grams per second (g/s) to kilograms per second (kg/s).

Factor1 g/s = 0.001 kg/s

Converter

g/s

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1kg/s

Rendered to 6 significant figures.

Formula

Formula
kg/s = g/s × 0.001

Multiply any value in grams per second by 0.001 to obtain the value in kilograms per second.

Worked example

Convert 1000 g/s to kg/s.

  1. 01Start with 1000 g/s.
  2. 02Multiply by the conversion factor: 1000 × 0.001 = 1 kg/s.
Result1000 g/s = 1 kg/s

FAQ

What is the conversion factor from g/s to kg/s?
1 g/s equals 0.001 kg/s. To convert, multiply the value in grams per second by 0.001.
How do I convert 1 g/s to kg/s?
1 g/s = 0.001 kg/s. For any value, multiply by 0.001.
How do I convert kg/s back to g/s?
Divide by the same factor — or equivalently, multiply by 1000. So 1 kg/s = 1000 g/s.
When would I need to convert gram per second to kilogram per second?
Mass flow conversions between g/s and kg/s are common in material balances, process stream summaries, bulk solids handling, custody transfer, and equipment sizing where kg/hr, t/hr, lb/hr, and lb/s may all appear in different datasheets or vendor documents.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
