FAQ

What is the conversion factor from st/day to kg/hr?
1 st/day equals 37.79936 kg/hr. To convert, multiply the value in short tons per day by 37.79936.
How do I convert 1 st/day to kg/hr?
1 st/day = 37.7994 kg/hr. For any value, multiply by 37.79936.
How do I convert kg/hr back to st/day?
Divide by the same factor — or equivalently, multiply by 0.02645547. So 1 kg/hr = 0.0264555 st/day.
When would I need to convert short ton per day to kilogram per hour?
Mass flow conversions between st/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).
