FAQ

What is the conversion factor from mg/hr to lb/hr?
1 mg/hr equals 2.204623e-6 lb/hr. To convert, multiply the value in milligrams per hour by 2.204623e-6.
How do I convert 1 mg/hr to lb/hr?
1 mg/hr = 2.20462e-6 lb/hr. For any value, multiply by 2.204623e-6.
How do I convert lb/hr back to mg/hr?
Divide by the same factor — or equivalently, multiply by 453592.4. So 1 lb/hr = 453592 mg/hr.
When would I need to convert milligram per hour to pound per hour?
Mass flow conversions between mg/hr and lb/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).
