Formula
Formula
lb/s = lb/min × 0.01666667
Multiply any value in pounds per minute by 0.01666667 to obtain the value in pounds per second.
Worked example
Convert 60 lb/min to lb/s.
- 01Start with 60 lb/min.
- 02Multiply by the conversion factor: 60 × 0.01666667 = 1 lb/s.
Result60 lb/min = 1 lb/s

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