Formula

Formula
st/day = kg/day × 0.001102311

Multiply any value in kilograms per day by 0.001102311 to obtain the value in short tons per day.

Worked example

Convert 1000 kg/day to st/day.

  1. 01Start with 1000 kg/day.
  2. 02Multiply by the conversion factor: 1000 × 0.001102311 = 1.10231 st/day.
Result1000 kg/day = 1.10231 st/day

FAQ

What is the conversion factor from kg/day to st/day?
1 kg/day equals 0.001102311 st/day. To convert, multiply the value in kilograms per day by 0.001102311.
How do I convert 1 kg/day to st/day?
1 kg/day = 0.00110231 st/day. For any value, multiply by 0.001102311.
How do I convert st/day back to kg/day?
Divide by the same factor — or equivalently, multiply by 907.1847. So 1 st/day = 907.185 kg/day.
When would I need to convert kilogram per day to short ton per day?
Mass flow conversions between kg/day 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).
