FAQ

What is the conversion factor from st/hr to kg/day?
1 st/hr equals 21772.43 kg/day. To convert, multiply the value in short tons per hour by 21772.43.
How do I convert 1 st/hr to kg/day?
1 st/hr = 21772.4 kg/day. For any value, multiply by 21772.43.
How do I convert kg/day back to st/hr?
Divide by the same factor — or equivalently, multiply by 4.592964e-5. So 1 kg/day = 4.59296e-5 st/hr.
When would I need to convert short ton per hour to kilogram per day?
Mass flow conversions between st/hr and kg/day 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).
