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

Result
3.77994t/hr

Rendered to 6 significant figures.

Formula

Formula
t/hr = st/day × 0.03779936

Multiply any value in short tons per day by 0.03779936 to obtain the value in metric tonnes per hour.

Worked example

Convert 100 st/day to t/hr.

  1. 01Start with 100 st/day.
  2. 02Multiply by the conversion factor: 100 × 0.03779936 = 3.77994 t/hr.
Result100 st/day = 3.77994 t/hr

FAQ

What is the conversion factor from st/day to t/hr?
1 st/day equals 0.03779936 t/hr. To convert, multiply the value in short tons per day by 0.03779936.
How do I convert 1 st/day to t/hr?
1 st/day = 0.0377994 t/hr. For any value, multiply by 0.03779936.
How do I convert t/hr back to st/day?
Divide by the same factor — or equivalently, multiply by 26.45547. So 1 t/hr = 26.4555 st/day.
When would I need to convert short ton per day to metric tonne per hour?
Mass flow conversions between st/day and t/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).
