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