FAQ

What is the conversion factor from gal/day (US) to cfm?
1 gal/day (US) equals 9.283372e-5 cfm. To convert, multiply the value in US gallons per day by 9.283372e-5.
How do I convert 1 gal/day (US) to cfm?
1 gal/day (US) = 9.28337e-5 cfm. For any value, multiply by 9.283372e-5.
How do I convert cfm back to gal/day (US)?
Divide by the same factor — or equivalently, multiply by 10771.95. So 1 cfm = 10771.9 gal/day (US).
When would I need to convert US gallon per day to cubic foot per minute?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. gal/day (US) to cfm is a frequently needed conversion for flow datasheet preparation.
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).
