Formula
st/hr = kg/day × 4.592964e-5

Multiply any value in kilograms per day by 4.592964e-5 to obtain the value in short tons per hour.

Worked example

Convert 100000 kg/day to st/hr.

  1. 01Start with 100000 kg/day.
  2. 02Multiply by the conversion factor: 100000 × 4.592964e-5 = 4.59296 st/hr.
Result100000 kg/day = 4.59296 st/hr

FAQ

What is the conversion factor from kg/day to st/hr?
1 kg/day equals 4.592964e-5 st/hr. To convert, multiply the value in kilograms per day by 4.592964e-5.
How do I convert 1 kg/day to st/hr?
1 kg/day = 4.59296e-5 st/hr. For any value, multiply by 4.592964e-5.
How do I convert st/hr back to kg/day?
Divide by the same factor — or equivalently, multiply by 21772.43. So 1 st/hr = 21772.4 kg/day.
When would I need to convert kilogram per day to short ton per hour?
Mass flow conversions between kg/day 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).
