Factor1 st/day = 0.9071847 t/day

Converter

st/day

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

Result
0.907185t/day

Rendered to 6 significant figures.

Formula

Formula
t/day = st/day × 0.9071847

Multiply any value in short tons per day by 0.9071847 to obtain the value in metric tonnes per day.

Worked example

Convert 1 st/day to t/day.

  1. 01Start with 1 st/day.
  2. 02Multiply by the conversion factor: 1 × 0.9071847 = 0.907185 t/day.
Result1 st/day = 0.907185 t/day

FAQ

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