FAQ

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