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.
Dram (dr)
The fluid dram is a small historical unit equal to 1/8 of a US fluid ounce or 3.6967 mL (US), with slightly different imperial values. It originated in apothecaries and early pharmaceutical texts, where drams measured potent liquid medicines, tinctures, and extracts. In daily life, drams appeared in old cocktail recipes, medicinal syrups, and household remedies. However, the inconsistency between US and UK drams, along with the rise of the metric system, pushed it out of modern use. Today, the dram survives mostly in whiskey culture—where a "dram" informally means a small pour, not a precise measurement—and in historical studies of medicine.
