Formula

Formula
t/hr = lb/s × 1.632933

Multiply any value in pounds per second by 1.632933 to obtain the value in metric tonnes per hour.

Worked example

Convert 10 lb/s to t/hr.

  1. 01Start with 10 lb/s.
  2. 02Multiply by the conversion factor: 10 × 1.632933 = 16.3293 t/hr.
Result10 lb/s = 16.3293 t/hr

FAQ

What is the conversion factor from lb/s to t/hr?
1 lb/s equals 1.632933 t/hr. To convert, multiply the value in pounds per second by 1.632933.
How do I convert 1 lb/s to t/hr?
1 lb/s = 1.63293 t/hr. For any value, multiply by 1.632933.
How do I convert t/hr back to lb/s?
Divide by the same factor — or equivalently, multiply by 0.6123952. So 1 t/hr = 0.612395 lb/s.
When would I need to convert pound per second to metric tonne per hour?
Mass flow conversions between lb/s 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).
