Formula

Formula
klb/min = st/day × 0.001388889

Multiply any value in short tons per day by 0.001388889 to obtain the value in kilopounds per minute.

Worked example

Convert 10000 st/day to klb/min.

  1. 01Start with 10000 st/day.
  2. 02Multiply by the conversion factor: 10000 × 0.001388889 = 13.8889 klb/min.
Result10000 st/day = 13.8889 klb/min

FAQ

What is the conversion factor from st/day to klb/min?
1 st/day equals 0.001388889 klb/min. To convert, multiply the value in short tons per day by 0.001388889.
How do I convert 1 st/day to klb/min?
1 st/day = 0.00138889 klb/min. For any value, multiply by 0.001388889.
How do I convert klb/min back to st/day?
Divide by the same factor — or equivalently, multiply by 720. So 1 klb/min = 720 st/day.
When would I need to convert short ton per day to kilopound per minute?
Mass flow conversions between st/day and klb/min 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).
