Formula
Formula
klb/min = lb/day × 6.944444e-7
Multiply any value in pounds per day by 6.944444e-7 to obtain the value in kilopounds per minute.
Worked example
Convert 1.00000e+6 lb/day to klb/min.
- 01Start with 1.00000e+6 lb/day.
- 02Multiply by the conversion factor: 1.00000e+6 × 6.944444e-7 = 0.694444 klb/min.
Result1.00000e+6 lb/day = 0.694444 klb/min

FAQ
What is the conversion factor from lb/day to klb/min?
1 lb/day equals 6.944444e-7 klb/min. To convert, multiply the value in pounds per day by 6.944444e-7.
How do I convert 1 lb/day to klb/min?
1 lb/day = 6.94444e-7 klb/min. For any value, multiply by 6.944444e-7.
How do I convert klb/min back to lb/day?
Divide by the same factor — or equivalently, multiply by 1440000. So 1 klb/min = 1.44000e+6 lb/day.
When would I need to convert pound per day to kilopound per minute?
Mass flow conversions between lb/day and klb/min 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).
