FAQ

What is the conversion factor from lb/min to kg/min?
1 lb/min equals 0.4535924 kg/min. To convert, multiply the value in pounds per minute by 0.4535924.
How do I convert 1 lb/min to kg/min?
1 lb/min = 0.453592 kg/min. For any value, multiply by 0.4535924.
How do I convert kg/min back to lb/min?
Divide by the same factor — or equivalently, multiply by 2.204623. So 1 kg/min = 2.20462 lb/min.
When would I need to convert pound per minute to kilogram per minute?
Mass flow conversions between lb/min and kg/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).
