FAQ

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