FAQ

What is the conversion factor from oz/min to mg/hr?
1 oz/min equals 1700971 mg/hr. To convert, multiply the value in ounces per minute by 1700971.
How do I convert 1 oz/min to mg/hr?
1 oz/min = 1.70097e+6 mg/hr. For any value, multiply by 1700971.
How do I convert mg/hr back to oz/min?
Divide by the same factor — or equivalently, multiply by 5.878994e-7. So 1 mg/hr = 5.87899e-7 oz/min.
When would I need to convert ounce per minute to milligram per hour?
Mass flow conversions between oz/min 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).
