Mass Flow Rate
lb/hrtost/day
Convert pounds per hour (lb/hr) to short tons per day (st/day).
Factor1 lb/hr = 0.012 st/day
Converter
lb/hr
Accepts numbers or expressions, e.g. 150 + 14.7
Result
st/day
Rendered to 6 significant figures.
Formula
Formula
st/day = lb/hr × 0.012
Multiply any value in pounds per hour by 0.012 to obtain the value in short tons per day.
Worked example
Convert 1000 lb/hr to st/day.
- 01Start with 1000 lb/hr.
- 02Multiply by the conversion factor: 1000 × 0.012 = 12 st/day.
Result1000 lb/hr = 12 st/day

FAQ
What is the conversion factor from lb/hr to st/day?
1 lb/hr equals 0.012 st/day. To convert, multiply the value in pounds per hour by 0.012.
How do I convert 1 lb/hr to st/day?
1 lb/hr = 0.012 st/day. For any value, multiply by 0.012.
How do I convert st/day back to lb/hr?
Divide by the same factor — or equivalently, multiply by 83.33333. So 1 st/day = 83.3333 lb/hr.
When would I need to convert pound per hour to short ton per day?
Mass flow conversions between lb/hr and st/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).
