Factor1 st/day = 2000 lb/day

Converter

st/day

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

Result
2000lb/day

Rendered to 6 significant figures.

Formula

Formula
lb/day = st/day × 2000

Multiply any value in short tons per day by 2000 to obtain the value in pounds per day.

Worked example

Convert 1 st/day to lb/day.

  1. 01Start with 1 st/day.
  2. 02Multiply by the conversion factor: 1 × 2000 = 2000 lb/day.
Result1 st/day = 2000 lb/day

FAQ

What is the conversion factor from st/day to lb/day?
1 st/day equals 2000 lb/day. To convert, multiply the value in short tons per day by 2000.
How do I convert 1 st/day to lb/day?
1 st/day = 2000 lb/day. For any value, multiply by 2000.
How do I convert lb/day back to st/day?
Divide by the same factor — or equivalently, multiply by 0.0005. So 1 lb/day = 0.0005 st/day.
When would I need to convert short ton per day to pound per day?
Mass flow conversions between st/day and lb/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).
