FAQ

What is the conversion factor from lb/day to kg/hr?
1 lb/day equals 0.01889968 kg/hr. To convert, multiply the value in pounds per day by 0.01889968.
How do I convert 1 lb/day to kg/hr?
1 lb/day = 0.0188997 kg/hr. For any value, multiply by 0.01889968.
How do I convert kg/hr back to lb/day?
Divide by the same factor — or equivalently, multiply by 52.91094. So 1 kg/hr = 52.9109 lb/day.
When would I need to convert pound per day to kilogram per hour?
Mass flow conversions between lb/day 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).
