Formula

Formula
mg/min = st/day × 629989.4

Multiply any value in short tons per day by 629989.4 to obtain the value in milligrams per minute.

Worked example

Convert 1 st/day to mg/min.

  1. 01Start with 1 st/day.
  2. 02Multiply by the conversion factor: 1 × 629989.4 = 629989 mg/min.
Result1 st/day = 629989 mg/min

FAQ

What is the conversion factor from st/day to mg/min?
1 st/day equals 629989.4 mg/min. To convert, multiply the value in short tons per day by 629989.4.
How do I convert 1 st/day to mg/min?
1 st/day = 629989 mg/min. For any value, multiply by 629989.4.
How do I convert mg/min back to st/day?
Divide by the same factor — or equivalently, multiply by 1.587328e-6. So 1 mg/min = 1.58733e-6 st/day.
When would I need to convert short ton per day to milligram per minute?
Mass flow conversions between st/day and mg/min 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).
