FAQ: You specify airflow in m³/h, how can I convert to CFM?

In accordance to the International System of Units (SI system), Noctua specifies volumetric flow rate (airflow) using the SI unit of cubic metres per hour (m³/h). The SI unit can easily be converted to cubic feet per minute (CFM): One m³/h is ~0.589 CFM and one CFM is ~1.699 m³/h. For convenient conversion, online tools such as www.convertunits.com can be used.
