Formula

Formula
st/hr = mg/s × 3.968321e-6

Multiply any value in milligrams per second by 3.968321e-6 to obtain the value in short tons per hour.

Worked example

Convert 1.00000e+6 mg/s to st/hr.

  1. 01Start with 1.00000e+6 mg/s.
  2. 02Multiply by the conversion factor: 1.00000e+6 × 3.968321e-6 = 3.96832 st/hr.
Result1.00000e+6 mg/s = 3.96832 st/hr

FAQ

What is the conversion factor from mg/s to st/hr?
1 mg/s equals 3.968321e-6 st/hr. To convert, multiply the value in milligrams per second by 3.968321e-6.
How do I convert 1 mg/s to st/hr?
1 mg/s = 3.96832e-6 st/hr. For any value, multiply by 3.968321e-6.
How do I convert st/hr back to mg/s?
Divide by the same factor — or equivalently, multiply by 251995.8. So 1 st/hr = 251996 mg/s.
When would I need to convert milligram per second to short ton per hour?
Mass flow conversions between mg/s 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).
