FAQ

What is the conversion factor from ft³/hr to L/hr?
1 ft³/hr equals 28.31685 L/hr. To convert, multiply the value in cubic feet per hour by 28.31685.
How do I convert 1 ft³/hr to L/hr?
1 ft³/hr = 28.3168 L/hr. For any value, multiply by 28.31685.
How do I convert L/hr back to ft³/hr?
Divide by the same factor — or equivalently, multiply by 0.03531467. So 1 L/hr = 0.0353147 ft³/hr.
When would I need to convert cubic foot per hour to litre per hour?
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 L/hr 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).
