Formula

Formula
t/day = lb/min × 0.653173

Multiply any value in pounds per minute by 0.653173 to obtain the value in metric tonnes per day.

Worked example

Convert 1 lb/min to t/day.

  1. 01Start with 1 lb/min.
  2. 02Multiply by the conversion factor: 1 × 0.653173 = 0.653173 t/day.
Result1 lb/min = 0.653173 t/day

FAQ

What is the conversion factor from lb/min to t/day?
1 lb/min equals 0.653173 t/day. To convert, multiply the value in pounds per minute by 0.653173.
How do I convert 1 lb/min to t/day?
1 lb/min = 0.653173 t/day. For any value, multiply by 0.653173.
How do I convert t/day back to lb/min?
Divide by the same factor — or equivalently, multiply by 1.530988. So 1 t/day = 1.53099 lb/min.
When would I need to convert pound per minute to metric tonne per day?
Mass flow conversions between lb/min and t/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).
