Mass Flow Rate

lb/hrtoklb/hr

Convert pounds per hour (lb/hr) to kilopounds per hour (klb/hr).

Factor1 lb/hr = 0.001 klb/hr

Converter

lb/hr

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

Result
1klb/hr

Rendered to 6 significant figures.

Formula

Formula
klb/hr = lb/hr × 0.001

Multiply any value in pounds per hour by 0.001 to obtain the value in kilopounds per hour.

Worked example

Convert 1000 lb/hr to klb/hr.

  1. 01Start with 1000 lb/hr.
  2. 02Multiply by the conversion factor: 1000 × 0.001 = 1 klb/hr.
Result1000 lb/hr = 1 klb/hr

FAQ

What is the conversion factor from lb/hr to klb/hr?
1 lb/hr equals 0.001 klb/hr. To convert, multiply the value in pounds per hour by 0.001.
How do I convert 1 lb/hr to klb/hr?
1 lb/hr = 0.001 klb/hr. For any value, multiply by 0.001.
How do I convert klb/hr back to lb/hr?
Divide by the same factor — or equivalently, multiply by 1000. So 1 klb/hr = 1000 lb/hr.
When would I need to convert pound per hour to kilopound per hour?
Mass flow conversions between lb/hr and klb/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).
