Rendered to 6 significant figures.

Formula

Formula
klb/hr = st/day × 0.08333333

Multiply any value in short tons per day by 0.08333333 to obtain the value in kilopounds per hour.

Worked example

Convert 100 st/day to klb/hr.

  1. 01Start with 100 st/day.
  2. 02Multiply by the conversion factor: 100 × 0.08333333 = 8.33333 klb/hr.
Result100 st/day = 8.33333 klb/hr

FAQ

What is the conversion factor from st/day to klb/hr?
1 st/day equals 0.08333333 klb/hr. To convert, multiply the value in short tons per day by 0.08333333.
How do I convert 1 st/day to klb/hr?
1 st/day = 0.0833333 klb/hr. For any value, multiply by 0.08333333.
How do I convert klb/hr back to st/day?
Divide by the same factor — or equivalently, multiply by 12. So 1 klb/hr = 12 st/day.
When would I need to convert short ton per day to kilopound per hour?
Mass flow conversions between st/day and klb/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).
