Factor1 st/hr = 21.77243 t/day

Converter

st/hr

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

Result
21.7724t/day

Rendered to 6 significant figures.

Formula

Formula
t/day = st/hr × 21.77243

Multiply any value in short tons per hour by 21.77243 to obtain the value in metric tonnes per day.

Worked example

Convert 1 st/hr to t/day.

  1. 01Start with 1 st/hr.
  2. 02Multiply by the conversion factor: 1 × 21.77243 = 21.7724 t/day.
Result1 st/hr = 21.7724 t/day

FAQ

What is the conversion factor from st/hr to t/day?
1 st/hr equals 21.77243 t/day. To convert, multiply the value in short tons per hour by 21.77243.
How do I convert 1 st/hr to t/day?
1 st/hr = 21.7724 t/day. For any value, multiply by 21.77243.
How do I convert t/day back to st/hr?
Divide by the same factor — or equivalently, multiply by 0.04592964. So 1 t/day = 0.0459296 st/hr.
When would I need to convert short ton per hour to metric tonne per day?
Mass flow conversions between st/hr 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).
