Formula
Formula
g/min = lb/day × 0.3149947
Multiply any value in pounds per day by 0.3149947 to obtain the value in grams per minute.
Worked example
Convert 1000 lb/day to g/min.
- 01Start with 1000 lb/day.
- 02Multiply by the conversion factor: 1000 × 0.3149947 = 314.995 g/min.
Result1000 lb/day = 314.995 g/min

FAQ
What is the conversion factor from lb/day to g/min?
1 lb/day equals 0.3149947 g/min. To convert, multiply the value in pounds per day by 0.3149947.
How do I convert 1 lb/day to g/min?
1 lb/day = 0.314995 g/min. For any value, multiply by 0.3149947.
How do I convert g/min back to lb/day?
Divide by the same factor — or equivalently, multiply by 3.174657. So 1 g/min = 3.17466 lb/day.
When would I need to convert pound per day to gram per minute?
Mass flow conversions between lb/day and g/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).
