Formula

Formula
mg/s = st/day × 10499.82

Multiply any value in short tons per day by 10499.82 to obtain the value in milligrams per second.

Worked example

Convert 1 st/day to mg/s.

  1. 01Start with 1 st/day.
  2. 02Multiply by the conversion factor: 1 × 10499.82 = 10499.8 mg/s.
Result1 st/day = 10499.8 mg/s

FAQ

What is the conversion factor from st/day to mg/s?
1 st/day equals 10499.82 mg/s. To convert, multiply the value in short tons per day by 10499.82.
How do I convert 1 st/day to mg/s?
1 st/day = 10499.8 mg/s. For any value, multiply by 10499.82.
How do I convert mg/s back to st/day?
Divide by the same factor — or equivalently, multiply by 9.52397e-5. So 1 mg/s = 9.52397e-5 st/day.
When would I need to convert short ton per day to milligram per second?
Mass flow conversions between st/day and mg/s 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).
