Formula
Formula
lb/day = mg/min × 0.003174657
Multiply any value in milligrams per minute by 0.003174657 to obtain the value in pounds per day.
Worked example
Convert 1000 mg/min to lb/day.
- 01Start with 1000 mg/min.
- 02Multiply by the conversion factor: 1000 × 0.003174657 = 3.17466 lb/day.
Result1000 mg/min = 3.17466 lb/day

FAQ
What is the conversion factor from mg/min to lb/day?
1 mg/min equals 0.003174657 lb/day. To convert, multiply the value in milligrams per minute by 0.003174657.
How do I convert 1 mg/min to lb/day?
1 mg/min = 0.00317466 lb/day. For any value, multiply by 0.003174657.
How do I convert lb/day back to mg/min?
Divide by the same factor — or equivalently, multiply by 314.9947. So 1 lb/day = 314.995 mg/min.
When would I need to convert milligram per minute to pound per day?
Mass flow conversions between mg/min and lb/day 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).
