About these units
Tablespoon (UK) (tbsp (UK))
The UK tablespoon traditionally equals 15 mL, though older definitions ranged from 17.7 to 25 mL depending on period and context. In modern British cooking, the tablespoon is standardized at 15 mL, aligning it with the metric tablespoon used in many countries. This measure remains essential in culinary arts for oils, spices, flavorings, and liquid ingredients, demonstrating how some units survive because of convenience and cultural familiarity, even in highly metricized societies.
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.
