Formula
lb/hr = oz/min × 3.75
Multiply any value in ounces per minute by 3.75 to obtain the value in pounds per hour.
Worked example
Convert 100 oz/min to lb/hr.
- 01Start with 100 oz/min.
- 02Multiply by the conversion factor: 100 × 3.75 = 375 lb/hr.
Result100 oz/min = 375 lb/hr

FAQ
What is the conversion factor from oz/min to lb/hr?
1 oz/min equals 3.75 lb/hr. To convert, multiply the value in ounces per minute by 3.75.
How do I convert 1 oz/min to lb/hr?
1 oz/min = 3.75 lb/hr. For any value, multiply by 3.75.
How do I convert lb/hr back to oz/min?
Divide by the same factor — or equivalently, multiply by 0.2666667. So 1 lb/hr = 0.266667 oz/min.
When would I need to convert ounce per minute to pound per hour?
Mass flow conversions between oz/min and lb/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).
