About these units
gph (US gallons per hour): Small pumps and fuel flows.
cfm (cubic feet per minute): Fans, ventilation and compressors.
US and UK gallons differ by about 20%; every gallon unit here is the US gallon unless stated. cfm is cubic feet per minute, the usual unit for fans and compressors; scfm and acfm (standard and actual) differ by the gas density, which this converter does not change.
