Formula
Formula
st/hr = lb/s × 1.8
Multiply any value in pounds per second by 1.8 to obtain the value in short tons per hour.
Worked example
Convert 1 lb/s to st/hr.
- 01Start with 1 lb/s.
- 02Multiply by the conversion factor: 1 × 1.8 = 1.8 st/hr.
Result1 lb/s = 1.8 st/hr

FAQ
What is the conversion factor from lb/s to st/hr?
1 lb/s equals 1.8 st/hr. To convert, multiply the value in pounds per second by 1.8.
How do I convert 1 lb/s to st/hr?
1 lb/s = 1.8 st/hr. For any value, multiply by 1.8.
How do I convert st/hr back to lb/s?
Divide by the same factor — or equivalently, multiply by 0.5555556. So 1 st/hr = 0.555556 lb/s.
When would I need to convert pound per second to short ton per hour?
Mass flow conversions between lb/s 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).
