FAQ

What is the conversion factor from ft³/hr to gal/day (US)?
1 ft³/hr equals 179.5325 gal/day (US). To convert, multiply the value in cubic feet per hour by 179.5325.
How do I convert 1 ft³/hr to gal/day (US)?
1 ft³/hr = 179.532 gal/day (US). For any value, multiply by 179.5325.
How do I convert gal/day (US) back to ft³/hr?
Divide by the same factor — or equivalently, multiply by 0.005570023. So 1 gal/day (US) = 0.00557002 ft³/hr.
When would I need to convert cubic foot per hour 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/hr 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).
