The City of Portland measures water consumption in CCFs or hundred cubic feet.

One CCF is equivalent to 748 gallons.

To determine the number of gallons of water used during a billing period, simply multiply the number of CCFs (the number is shown on your bill under the Usage column) by 748.  Or you can enter the consumption (CCFs) from your water bill in the box below and the number of gallons will be calculated for you.
