What is a CCF to gallons converter?
A CCF to gallons converter changes a water volume measured in CCF, or hundred cubic feet, into gallons. Water utilities in the United States often bill customers in CCF, so converting to gallons makes it easier to understand actual usage.
What does CCF mean?
CCF stands for "hundred cubic feet." The "C" comes from the Roman numeral for one hundred. One CCF equals 100 cubic feet of water. It is the same unit as HCF, which some utilities use instead. Both mean exactly the same volume.
CCF to gallons formula
One cubic foot holds 7.48052 gallons. Since one CCF is 100 cubic feet, one CCF holds 100 times that amount:
1 CCF = 748.052 gallons
To convert CCF to gallons, multiply the CCF value by 748.052:
Gallons = CCF × 748.052
To convert gallons back to CCF, divide by the same number:
CCF = Gallons ÷ 748.052
One gallon equals about 0.00133681 CCF.
Example calculation
A water bill shows usage of 8 CCF. To find the amount in gallons:
8 × 748.052 = 5,984.416 gallons
So 8 CCF of water use equals 5,984.416 gallons.
For a reverse example, a 15,000-gallon pool holds:
15,000 ÷ 748.052 ≈ 20.05 CCF

Why water bills use CCF instead of gallons
A typical household uses thousands of gallons of water each month. Writing that number in gallons makes bills harder to read. CCF turns a large gallon count into a smaller, simpler number. A bill that reads "10 CCF" represents 7,480.52 gallons, but the smaller unit is easier to print and compare month to month.
How to read a water meter in CCF
Most residential water meters display a running total in cubic feet or CCF, not gallons. To estimate gallons used between two readings:
- Subtract the earlier meter reading from the later one to get cubic feet or CCF used.
- If the result is in cubic feet, divide by 100 to convert to CCF.
- Multiply the CCF figure by 748.052 to get gallons.
