Formula

Formula
mg/s = klb/hr × 125997.9

Multiply any value in kilopounds per hour by 125997.9 to obtain the value in milligrams per second.

Worked example

Convert 1 klb/hr to mg/s.

  1. 01Start with 1 klb/hr.
  2. 02Multiply by the conversion factor: 1 × 125997.9 = 125998 mg/s.
Result1 klb/hr = 125998 mg/s

FAQ

What is the conversion factor from klb/hr to mg/s?
1 klb/hr equals 125997.9 mg/s. To convert, multiply the value in kilopounds per hour by 125997.9.
How do I convert 1 klb/hr to mg/s?
1 klb/hr = 125998 mg/s. For any value, multiply by 125997.9.
How do I convert mg/s back to klb/hr?
Divide by the same factor — or equivalently, multiply by 7.936641e-6. So 1 mg/s = 7.93664e-6 klb/hr.
When would I need to convert kilopound per hour to milligram per second?
Mass flow conversions between klb/hr and mg/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).
