FAQ

What is the conversion factor from lb/min to kg/day?
1 lb/min equals 653.173 kg/day. To convert, multiply the value in pounds per minute by 653.173.
How do I convert 1 lb/min to kg/day?
1 lb/min = 653.173 kg/day. For any value, multiply by 653.173.
How do I convert kg/day back to lb/min?
Divide by the same factor — or equivalently, multiply by 0.001530988. So 1 kg/day = 0.00153099 lb/min.
When would I need to convert pound per minute to kilogram per day?
Mass flow conversions between lb/min and kg/day 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).
