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.
Cord (cd)
The cord is a large unit used in North America to measure firewood, defined as a neatly stacked pile measuring 128 cubic feet (usually arranged as 4 ft × 4 ft × 8 ft). Its strict definition helps prevent fraud in firewood sales and ensures fairness in trade. The cord accounts for both wood and air space, though the amount of actual wood can vary depending on how tightly it is stacked. Despite the prevalence of metric units worldwide, the cord remains a robust standard in forestry, firewood commerce, and rural heating practices across the US and Canada.
