Mass Flow Rate

kg/stomg/s

Convert kilograms per second (kg/s) to milligrams per second (mg/s).

Factor1 kg/s = 1000000 mg/s

Converter

kg/s

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

Result
1.00000e+6mg/s

Rendered to 6 significant figures.

Formula

Formula
mg/s = kg/s × 1000000

Multiply any value in kilograms per second by 1000000 to obtain the value in milligrams per second.

Worked example

Convert 1 kg/s to mg/s.

  1. 01Start with 1 kg/s.
  2. 02Multiply by the conversion factor: 1 × 1000000 = 1.00000e+6 mg/s.
Result1 kg/s = 1.00000e+6 mg/s

FAQ

What is the conversion factor from kg/s to mg/s?
1 kg/s equals 1000000 mg/s. To convert, multiply the value in kilograms per second by 1000000.
How do I convert 1 kg/s to mg/s?
1 kg/s = 1.00000e+6 mg/s. For any value, multiply by 1000000.
How do I convert mg/s back to kg/s?
Divide by the same factor — or equivalently, multiply by 1e-6. So 1 mg/s = 1e-6 kg/s.
When would I need to convert kilogram per second to milligram per second?
Mass flow conversions between kg/s and mg/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).
