FAQ

What is the conversion factor from L/hr to cfm?
1 L/hr equals 0.0005885778 cfm. To convert, multiply the value in litres per hour by 0.0005885778.
How do I convert 1 L/hr to cfm?
1 L/hr = 0.000588578 cfm. For any value, multiply by 0.0005885778.
How do I convert cfm back to L/hr?
Divide by the same factor — or equivalently, multiply by 1699.011. So 1 cfm = 1699.01 L/hr.
When would I need to convert litre per hour 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. L/hr 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).
