About these units
Acre-Inch (ac*in)
An acre-inch equals 1/12 of an acre-foot, representing the water required to cover one acre to a depth of one inch. Irrigation planners and farmers often use acre-inches to fine-tune watering schedules for crops. Because plants require precise hydration, the acre-inch allows for granular control of irrigation needed for soil management and crop health. Agronomists also use acre-inches to convert rainfall into usable water volume estimates for agricultural regions, linking meteorology with farm management.
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.
