Factor1 mg/hr = 0.01666667 mg/min

Converter

mg/hr

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

Result
1mg/min

Rendered to 6 significant figures.

Formula

Formula
mg/min = mg/hr × 0.01666667

Multiply any value in milligrams per hour by 0.01666667 to obtain the value in milligrams per minute.

Worked example

Convert 60 mg/hr to mg/min.

  1. 01Start with 60 mg/hr.
  2. 02Multiply by the conversion factor: 60 × 0.01666667 = 1 mg/min.
Result60 mg/hr = 1 mg/min

FAQ

What is the conversion factor from mg/hr to mg/min?
1 mg/hr equals 0.01666667 mg/min. To convert, multiply the value in milligrams per hour by 0.01666667.
How do I convert 1 mg/hr to mg/min?
1 mg/hr = 0.0166667 mg/min. For any value, multiply by 0.01666667.
How do I convert mg/min back to mg/hr?
Divide by the same factor — or equivalently, multiply by 60. So 1 mg/min = 60 mg/hr.
When would I need to convert milligram per hour to milligram per minute?
Mass flow conversions between mg/hr and mg/min 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).
