cubic foot per hour

Volumetric flow rateexact by definition

The cubic foot per hour is exactly 0.028316846592/3600 cubic metres per second. It is the reading on a residential and commercial gas meter, and the sizing unit for gas piping tables in North America.

Watch out: Gas volumes are only meaningful with a stated temperature and pressure, which is why gas flows are properly given as SCFH, standard cubic feet per hour. Different industries define "standard" differently: 60 °F is normal for gas utilities, 68 °F for compressed air in the United States, and 0 °C for the European normal cubic metre. This site converts geometric volume, so a standard-condition flow needs correcting before or after, not by this factor.
