About these units
CCF (ccf)
The abbreviation CCF stands for centum cubic feet, meaning 100 cubic feet. It is widely used by water and natural gas utilities to measure residential and industrial consumption. Water bills in many US cities list usage in CCF, balancing numerical convenience with practical scale. For example, a household may consume 5–12 CCF per month, depending on climate and household size. Because natural gas companies also use CCF, the unit plays a central role in energy billing, conservation programs, and environmental reporting. It is a key bridge between technical engineering measurements and everyday consumer usage.
Gigaliter (GL)
A gigaliter equals one billion liters or one million cubic meters. It is widely used when discussing very large natural or artificial water systems. Countries quantify national water reserves, lake capacities, and large-scale water transfers in gigaliters. For example, major reservoirs, such as those used for hydroelectric power generation, often have volumes in the tens of gigaliters. Environmental scientists use GL to describe groundwater extraction, rainfall totals across large regions, and freshwater availability. The GL helps quantify planetary-scale hydrological processes in a manageable numerical range.
