About these units
Quart (UK) (qt (UK))
A UK quart equals 1/4 of a UK gallon, approximately 1.13652 liters, making it significantly larger than the US quart. Historically used for beer, milk, and household liquids, the UK quart was a staple of British commerce for centuries. In many traditional recipes and food instructions, quarts remain in archival use. The quart illustrates the divergence between US and UK systems following the 18th-century measurement reforms, reflecting how cultural and regulatory environments shape unit evolution.
Acre-Foot (ac*ft)
An acre-foot represents the volume of water needed to cover one acre of land to a depth of one foot—approximately 1,233.48 cubic meters or 325,851 gallons. This unit is foundational in water resource management throughout the western United States, where large-scale irrigation, reservoir planning, and drought analysis depend on acre-foot measurements. For example, major reservoirs like Lake Mead and Lake Powell hold billions of acre-feet. In agriculture, irrigation districts track water rights and allocations using acre-feet, making it a key component of water law. Its scale is ideal for representing the enormous water needs associated with farming, urban expansion, and environmental preservation.
