Formula

Formula
t/hr = lb/hr × 0.0004535924

Multiply any value in pounds per hour by 0.0004535924 to obtain the value in metric tonnes per hour.

Worked example

Convert 10000 lb/hr to t/hr.

  1. 01Start with 10000 lb/hr.
  2. 02Multiply by the conversion factor: 10000 × 0.0004535924 = 4.53592 t/hr.
Result10000 lb/hr = 4.53592 t/hr

FAQ

What is the conversion factor from lb/hr to t/hr?
1 lb/hr equals 0.0004535924 t/hr. To convert, multiply the value in pounds per hour by 0.0004535924.
How do I convert 1 lb/hr to t/hr?
1 lb/hr = 0.000453592 t/hr. For any value, multiply by 0.0004535924.
How do I convert t/hr back to lb/hr?
Divide by the same factor — or equivalently, multiply by 2204.623. So 1 t/hr = 2204.62 lb/hr.
When would I need to convert pound per hour to metric tonne per hour?
Mass flow conversions between lb/hr and t/hr 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).
