Formula
Formula
lb/hr = st/hr × 2000
Multiply any value in short tons per hour by 2000 to obtain the value in pounds per hour.
Worked example
Convert 1 st/hr to lb/hr.
- 01Start with 1 st/hr.
- 02Multiply by the conversion factor: 1 × 2000 = 2000 lb/hr.
Result1 st/hr = 2000 lb/hr

FAQ
What is the conversion factor from st/hr to lb/hr?
1 st/hr equals 2000 lb/hr. To convert, multiply the value in short tons per hour by 2000.
How do I convert 1 st/hr to lb/hr?
1 st/hr = 2000 lb/hr. For any value, multiply by 2000.
How do I convert lb/hr back to st/hr?
Divide by the same factor — or equivalently, multiply by 0.0005. So 1 lb/hr = 0.0005 st/hr.
When would I need to convert short ton per hour to pound per hour?
Mass flow conversions between st/hr and lb/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).
