Mass Flow Rate

mg/stokg/s

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

Factor1 mg/s = 1e-6 kg/s

Converter

mg/s

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

Result
1kg/s

Rendered to 6 significant figures.

Formula

Formula
kg/s = mg/s × 1e-6

Multiply any value in milligrams per second by 1e-6 to obtain the value in kilograms per second.

Worked example

Convert 1.00000e+6 mg/s to kg/s.

  1. 01Start with 1.00000e+6 mg/s.
  2. 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 kg/s.
Result1.00000e+6 mg/s = 1 kg/s

FAQ

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