About these units
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.
Tablespoon (US) (tbsp)
The US tablespoon is defined as 14.7868 mL, though commonly rounded to 15 mL in nutritional labeling and informal cooking contexts. In American cooking, the tablespoon is indispensable for measuring oils, spices, and small liquid quantities. It is also widely used in medicine for dosing liquid medications at home, though modern practice increasingly recommends milliliters for clarity. Its relationship—3 teaspoons = 1 tablespoon and 16 tablespoons = 1 cup—allows American cooks to scale recipes easily, making it a cornerstone unit of the US culinary measurement system.
