FAQ
What is the conversion factor from lb/hr to mg/min?
1 lb/hr equals 7559.873 mg/min. To convert, multiply the value in pounds per hour by 7559.873.
How do I convert 1 lb/hr to mg/min?
1 lb/hr = 7559.87 mg/min. For any value, multiply by 7559.873.
How do I convert mg/min back to lb/hr?
Divide by the same factor — or equivalently, multiply by 0.0001322774. So 1 mg/min = 0.000132277 lb/hr.
When would I need to convert pound per hour to milligram per minute?
Mass flow conversions between lb/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).
