FAQ

What is the conversion factor from ft³/hr to m³/hr?
1 ft³/hr equals 0.02831685 m³/hr. To convert, multiply the value in cubic feet per hour by 0.02831685.
How do I convert 1 ft³/hr to m³/hr?
1 ft³/hr = 0.0283168 m³/hr. For any value, multiply by 0.02831685.
How do I convert m³/hr back to ft³/hr?
Divide by the same factor — or equivalently, multiply by 35.31467. So 1 m³/hr = 35.3147 ft³/hr.
When would I need to convert cubic foot per hour to cubic metre 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 m³/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).
