Factor1 lb/hr = 0.0005 st/hr
Converter
lb/hr
Accepts numbers or expressions, e.g. 150 + 14.7
Result
st/hr
Rendered to 6 significant figures.
Formula
Formula
st/hr = lb/hr × 0.0005
Multiply any value in pounds per hour by 0.0005 to obtain the value in short tons per hour.
Worked example
Convert 2000 lb/hr to st/hr.
- 01Start with 2000 lb/hr.
- 02Multiply by the conversion factor: 2000 × 0.0005 = 1 st/hr.
Result2000 lb/hr = 1 st/hr

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