Your water bill shows CCF, but thinking in gallons is far easier. This free CCF to gallons converter gives you an instant, accurate result — no math required.

Quick Definition: CCF stands for Centum Cubic Feet, meaning 100 cubic feet of water. It is the standard unit used by most water utilities in the US. One CCF equals exactly 748.052 US gallons. This tool converts CCF to gallons and gallons to CCF in one click.

CCF and Gallons: What Your Water Bill Is Actually Measuring

Most water utilities in the United States measure consumption in CCF — hundred cubic feet. For the average homeowner, this unit is abstract. You fill pools, run showers, and water lawns in gallons, not cubic feet and gallons combined.

That disconnect makes it hard to track water consumption or spot billing errors. Converting your CCF measurements to US gallons bridges that gap immediately. For related volume conversions, you can also check out the ML to Pounds Calculator for liquid measurement needs.

The Conversion Formula (and Where It Has Limits)

The math behind this conversion tool is fixed and precise:

CCF to Gallons: Gallons = CCF x 748.052

Gallons to CCF: CCF = Gallons / 748.052

The conversion factor 748.0519 gallons per CCF is based on the exact definition that 1 cubic foot of water equals 7.48052 US gallons, and one CCF equals 100 cubic feet of water.

Limitation: This formula applies strictly to US gallons. If your water utility bills in imperial (UK) gallons, the conversion factor differs. Always confirm your utility’s measurement standard before using the result for billing disputes or specification requirements.
