Factor1 kg/hr = 1000000 mg/hr

Converter

kg/hr

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

Result
1.00000e+6mg/hr

Rendered to 6 significant figures.

Formula

Formula
mg/hr = kg/hr × 1000000

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

Worked example

Convert 1 kg/hr to mg/hr.

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

FAQ

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