Factor1 st/day = 0.04166667 st/hr

Converter

st/day

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

Result
1st/hr

Rendered to 6 significant figures.

Formula

Formula
st/hr = st/day × 0.04166667

Multiply any value in short tons per day by 0.04166667 to obtain the value in short tons per hour.

Worked example

Convert 24 st/day to st/hr.

  1. 01Start with 24 st/day.
  2. 02Multiply by the conversion factor: 24 × 0.04166667 = 1 st/hr.
Result24 st/day = 1 st/hr

FAQ

What is the conversion factor from st/day to st/hr?
1 st/day equals 0.04166667 st/hr. To convert, multiply the value in short tons per day by 0.04166667.
How do I convert 1 st/day to st/hr?
1 st/day = 0.0416667 st/hr. For any value, multiply by 0.04166667.
How do I convert st/hr back to st/day?
Divide by the same factor — or equivalently, multiply by 24. So 1 st/hr = 24 st/day.
When would I need to convert short ton per day to short ton per hour?
Mass flow conversions between st/day and st/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).
