Formula

Formula
lb/s = kg/min × 0.03674371

Multiply any value in kilograms per minute by 0.03674371 to obtain the value in pounds per second.

Worked example

Convert 100 kg/min to lb/s.

  1. 01Start with 100 kg/min.
  2. 02Multiply by the conversion factor: 100 × 0.03674371 = 3.67437 lb/s.
Result100 kg/min = 3.67437 lb/s

FAQ

What is the conversion factor from kg/min to lb/s?
1 kg/min equals 0.03674371 lb/s. To convert, multiply the value in kilograms per minute by 0.03674371.
How do I convert 1 kg/min to lb/s?
1 kg/min = 0.0367437 lb/s. For any value, multiply by 0.03674371.
How do I convert lb/s back to kg/min?
Divide by the same factor — or equivalently, multiply by 27.21554. So 1 lb/s = 27.2155 kg/min.
When would I need to convert kilogram per minute to pound per second?
Mass flow conversions between kg/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).
