FAQ
What is the conversion factor from st/hr to lb/min?
1 st/hr equals 33.33333 lb/min. To convert, multiply the value in short tons per hour by 33.33333.
How do I convert 1 st/hr to lb/min?
1 st/hr = 33.3333 lb/min. For any value, multiply by 33.33333.
How do I convert lb/min back to st/hr?
Divide by the same factor — or equivalently, multiply by 0.03. So 1 lb/min = 0.03 st/hr.
When would I need to convert short ton per hour to pound per minute?
Mass flow conversions between st/hr and lb/min 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).
