Convert CCF (centum cubic feet) to gallons and vice versa. Includes utility cost estimation, household usage table, and multi-unit results.
CCF stands for centum cubic feet, or 100 cubic feet, and it is the billing unit used on many US water and natural-gas statements. One CCF equals exactly 748.052 US gallons, so this page helps turn a utility reading into a number that is easier to picture.
The converter shows gallons, liters, quarts, cubic meters, and cubic feet, and it can also estimate cost from a rate per CCF. It also gives you a simple way to compare a meter reading against common chores, appliance loads, or savings goals. That makes it useful when you want to relate a bill line item to actual household water use. It also gives you a simple way to compare a meter reading against common chores, appliance loads, or savings goals.
Use it when a meter reading or bill amount needs to become a gallon-based figure you can compare with everyday consumption. That makes it easier to discuss conservation, compare tiers, or estimate the impact of a leak.
Utility billing in CCF is hard to interpret at a glance. It is particularly helpful when you want to see whether a change in habits is moving the bill in the right direction. This converter turns that usage into gallons and other familiar units so you can compare it with household activities, rates, and conservation targets. It is particularly helpful when you want to see whether a change in habits is moving the bill in the right direction.
gallons = CCF × 748.052 CCF = gallons ÷ 748.052 cost = CCF × rate_per_CCF cost_per_gallon = rate_per_CCF ÷ 748.052
Result: 7,480.52 gallons, $50.00 cost
10 CCF × 748.052 = 7,480.52 US gallons. At $5.00/CCF the total cost is $50.00, which works out to $0.0067 per gallon.
A CCF—centum cubic feet—represents the volume of 100 cubic feet of water (or gas). Utility meters record consumption in cubic feet as water flows through, and the billing department reports the total in CCF increments. Because 1 cubic foot holds 7.48052 US gallons, multiplying by 100 gives the familiar 748.052 gallons per CCF.
Most residential water bills list a "usage" column in CCF alongside a per-CCF tiered rate. The first tier may be $3–$4/CCF for essential use; higher tiers charge $8–$15/CCF to discourage excess consumption. Converting CCF to gallons lets you compare your usage to conservation benchmarks published by the EPA, which recommends families aim for under 8 CCF per month.
Using the household-activity table, identify high-consumption habits such as long showers or daily lawn watering. Switching to a low-flow showerhead saves roughly 0.02 CCF per shower. Installing a dual-flush toilet can cut each flush from 1.6 gallons to 0.8 gallons, halving that line item on your bill. Over a year, small changes can cut 10–20 CCF—saving $50–$150 depending on your rate tier.
Exactly 748.052 US gallons. One CCF equals 100 cubic feet of volume.
CCF stands for centum (Latin for 100) cubic feet. It measures the total volume of water that passed through your meter.
1 CCF = 748.052 gallons × 3.78541 L/gal ≈ 2,831.68 liters. That helps translate a utility bill into metric terms for reporting or comparison. That helps translate a utility bill into metric terms for reporting or comparison.
An average US household uses roughly 8–12 CCF per month, depending on climate, irrigation, and household size. Outdoor watering can push that number much higher in dry seasons. Outdoor watering can push that number much higher in dry seasons.
Yes. HCF (hundred cubic feet) and CCF (centum cubic feet) are exactly the same unit.
Divide your CCF rate by 748.052. At $5/CCF, water costs about $0.0067 per gallon—less than a penny.
