Formula
Formula
lb/min = lb/s × 60
Multiply any value in pounds per second by 60 to obtain the value in pounds per minute.
Worked example
Convert 1 lb/s to lb/min.
- 01Start with 1 lb/s.
- 02Multiply by the conversion factor: 1 × 60 = 60 lb/min.
Result1 lb/s = 60 lb/min

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