FAQ

What is the conversion factor from ft³/min to gal/day (US)?
1 ft³/min equals 10771.95 gal/day (US). To convert, multiply the value in cubic feet per minute by 10771.95.
How do I convert 1 ft³/min to gal/day (US)?
1 ft³/min = 10771.9 gal/day (US). For any value, multiply by 10771.95.
How do I convert gal/day (US) back to ft³/min?
Divide by the same factor — or equivalently, multiply by 9.283372e-5. So 1 gal/day (US) = 9.28337e-5 ft³/min.
When would I need to convert cubic foot per minute to US gallon per day?
Flow-rate conversions show up in pump curve interpretation, control valve sizing (Cv vs Kv), and aligning vendor specifications with process simulation outputs. ft³/min to gal/day (US) 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).
