FAQ

What is the conversion factor from klb/hr to kg/s?
1 klb/hr equals 0.1259979 kg/s. To convert, multiply the value in kilopounds per hour by 0.1259979.
How do I convert 1 klb/hr to kg/s?
1 klb/hr = 0.125998 kg/s. For any value, multiply by 0.1259979.
How do I convert kg/s back to klb/hr?
Divide by the same factor — or equivalently, multiply by 7.936641. So 1 kg/s = 7.93664 klb/hr.
When would I need to convert kilopound per hour to kilogram per second?
Mass flow conversions between klb/hr and kg/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).
