CCF shows up on utility bills in the United States. One CCF equals 100 cubic feet. Water departments and gas companies both use it. The tricky part is comparing CCF to units you already know. A gas bill might show 63 CCF. A water bill might show 5.5 CCF. This converter turns those numbers into gallons, therms, cubic meters, liters, and pounds of water. It also handles MCF, HCF, acre-feet, barrels, BTU, kWh, and metric tonnes. Enter the amount, choose the units, and read the result.
How to Use the CCF Converter
Pick a from unit from the first dropdown.
Pick a to unit from the second dropdown.
Type the amount you want to convert.
Read the converted value in the hero panel.
Check the full breakdown table for the same amount in every unit.

Every unit is stored as a factor relative to CCF. The tool converts to CCF first, then to the target unit.
Formula: CCF value = amount × from unit factor
Formula: Converted value = CCF value ÷ to unit factor
Formula: 1 CCF = 100 cubic feet = 748.052 US gallons = 2.83168 cubic meters
Formula: 1 CCF ≈ 1.037 therms ≈ 103,700 BTU
The factor table covers volume units, natural gas energy units, and water weight units. Gas energy uses the US average heating value of 1,037 BTU per cubic foot. That average varies by supplier and region, usually between 1,000 and 1,100 BTU per cubic foot. Water weight assumes pure water at standard temperature.
The tool accepts any non-negative amount. If the amount is zero, the result is zero. Invalid entries return an error message instead of a number.
A gas bill shows 63 CCF. You want to know the equivalent in therms.
From unit: CCF
To unit: Therms
Amount: 63
CCF value: 63 × 1 = 63 CCF
Converted value: 63 ÷ 0.96432 = 65.33 therms
The full breakdown also shows 4,712.7 gallons, 6,300 cubic feet, 178.4 cubic meters, 178,400 liters, 6.78 MMBTU, and 392,958 pounds of water equivalent.
If the same 63 CCF were converted to gallons: 63 × 748.052 = 47,127.3 gallons. That number matters if you’re sizing a tank or comparing a water bill to a delivery.
CCF means centum cubic feet. It equals 100 cubic feet. The unit appears on water and natural gas bills across the United States. HCF means the same thing. Utilities use CCF because it keeps billing numbers manageable. One CCF of water weighs about 6,237 pounds, or roughly 2.83 metric tonnes.
One CCF equals 748.052 US gallons. That figure comes from 100 cubic feet times 7.48052 gallons per cubic foot. A 10 CCF water bill represents 7,480.52 gallons. A 20,000-gallon pool holds about 26.7 CCF. The converter shows this conversion instantly for any amount.
Multiply the CCF value by 1.037. That’s the US average heating value of natural gas. One CCF equals about 1.037 therms. A 63 CCF gas bill equals roughly 65.3 therms. If your utility uses a different heating value, adjust the multiplier. The converter uses the US average because it fits most residential bills.
MCF means thousand cubic feet. One MCF equals 10 CCF. Gas utilities often bill in CCF for residential customers and MCF for commercial or industrial accounts. If a bill shows 5 MCF, that’s 50 CCF. The converter handles both directions, so you can switch between them without manual math.
Yes. CCF and HCF both mean hundred cubic feet. Utilities use them interchangeably. You might see HCF on one bill and CCF on another from the same company. The numbers mean the same thing. Some older bills use the term “hundred cubic feet” spelled out.
Divide gallons by 748.052. A 10,000-gallon water delivery equals 13.37 CCF. A 500-gallon hot tub holds about 0.67 CCF. The converter handles this direction too. Just pick gallons as the from unit and CCF as the to unit.
A typical US household uses 4 to 8 CCF of water per month. Gas use runs 50 to 80 CCF per month in winter for heating and cooking. Summer gas use drops to 10 to 20 CCF for cooking and water heating. Your actual usage depends on climate, appliance efficiency, and household size.
Multiply CCF by 2.83168. A 5 CCF water bill equals 14.16 cubic meters. A 100 CCF gas bill equals 283.17 cubic meters. The converter also handles cubic meters, liters, and milliliters in the same pass.
Natural gas heating value changes with the source. Pipeline gas from different fields has different BTU content. Most utilities publish a monthly multiplier. The range runs from about 1,000 to 1,100 BTU per cubic foot. The converter uses 1,037 BTU per cubic foot, which is the US average. For exact billing, check your utility’s multiplier.
Mixing up CCF and MCF is the top error. One is 100 cubic feet, the other is 1,000 cubic feet. That’s a factor of 10. Second, using the wrong heating value for gas. Third, forgetting that water weight changes with temperature, though the difference is small. Fourth, assuming CCF and gallons are close. One CCF is nearly 750 gallons.
