How Many Gallons Are in an HCF?

HCF is an acronym for “hundred cubic feet” and is a standard unit for measuring a volume of water, typically for water metering and billing purposes. One hundred cubic feet of water is equal to 748 gallons. The average American uses 100 gallons of water every day.

HCF is the most common unit for measuring water usage. Another term that is used is CCF, or “centum cubic feet,” where the word “centum” is of Roman origin and means “hundred.” Understanding the terminology used in water billing is critical to understanding actual usage rates, which can prompt users to find ways to reduce consumption and conserve valuable resources.
