FAQ

What is the conversion factor from lb/s to kg/hr?
1 lb/s equals 1632.933 kg/hr. To convert, multiply the value in pounds per second by 1632.933.
How do I convert 1 lb/s to kg/hr?
1 lb/s = 1632.93 kg/hr. For any value, multiply by 1632.933.
How do I convert kg/hr back to lb/s?
Divide by the same factor — or equivalently, multiply by 0.0006123952. So 1 kg/hr = 0.000612395 lb/s.
When would I need to convert pound per second to kilogram per hour?
Mass flow conversions between lb/s and kg/hr 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).
