Rendered to 6 significant figures.

Formula

Formula
kg/hr = mg/s × 0.0036

Multiply any value in milligrams per second by 0.0036 to obtain the value in kilograms per hour.

Worked example

Convert 1000 mg/s to kg/hr.

  1. 01Start with 1000 mg/s.
  2. 02Multiply by the conversion factor: 1000 × 0.0036 = 3.6 kg/hr.
Result1000 mg/s = 3.6 kg/hr

FAQ

What is the conversion factor from mg/s to kg/hr?
1 mg/s equals 0.0036 kg/hr. To convert, multiply the value in milligrams per second by 0.0036.
How do I convert 1 mg/s to kg/hr?
1 mg/s = 0.0036 kg/hr. For any value, multiply by 0.0036.
How do I convert kg/hr back to mg/s?
Divide by the same factor — or equivalently, multiply by 277.7778. So 1 kg/hr = 277.778 mg/s.
When would I need to convert milligram per second to kilogram per hour?
Mass flow conversions between mg/s and kg/hr 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).
