Formula

Formula
lb/s = t/day × 0.02551647

Multiply any value in metric tonnes per day by 0.02551647 to obtain the value in pounds per second.

Worked example

Convert 100 t/day to lb/s.

  1. 01Start with 100 t/day.
  2. 02Multiply by the conversion factor: 100 × 0.02551647 = 2.55165 lb/s.
Result100 t/day = 2.55165 lb/s

FAQ

What is the conversion factor from t/day to lb/s?
1 t/day equals 0.02551647 lb/s. To convert, multiply the value in metric tonnes per day by 0.02551647.
How do I convert 1 t/day to lb/s?
1 t/day = 0.0255165 lb/s. For any value, multiply by 0.02551647.
How do I convert lb/s back to t/day?
Divide by the same factor — or equivalently, multiply by 39.19038. So 1 lb/s = 39.1904 t/day.
When would I need to convert metric tonne per day to pound per second?
Mass flow conversions between t/day and lb/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).
