Factor1 t/day = 1.102311 st/day

Converter

t/day

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1.10231st/day

Rendered to 6 significant figures.

Formula

Formula
st/day = t/day × 1.102311

Multiply any value in metric tonnes per day by 1.102311 to obtain the value in short tons per day.

Worked example

Convert 1 t/day to st/day.

  1. 01Start with 1 t/day.
  2. 02Multiply by the conversion factor: 1 × 1.102311 = 1.10231 st/day.
Result1 t/day = 1.10231 st/day

FAQ

What is the conversion factor from t/day to st/day?
1 t/day equals 1.102311 st/day. To convert, multiply the value in metric tonnes per day by 1.102311.
How do I convert 1 t/day to st/day?
1 t/day = 1.10231 st/day. For any value, multiply by 1.102311.
How do I convert st/day back to t/day?
Divide by the same factor — or equivalently, multiply by 0.9071847. So 1 st/day = 0.907185 t/day.
When would I need to convert metric tonne per day to short ton per day?
Mass flow conversions between t/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).
