About these units
Board Foot (board foot)
A board foot is a unit of volume used in lumber, defined as a board measuring 1 foot long × 1 foot wide × 1 inch thick, equal to 144 cubic inches, or about 2.36 liters. The unit reflects a material-centric approach to volume: rather than measuring empty space, the board foot measures solid wood content, crucial for pricing logs, boards, and woodworking materials. Forestry operations, sawmills, and lumber yards rely heavily on board-feet calculations to estimate yields from logs, determine pricing, and evaluate timber resources. The unit persists due to deep integration with North American construction and carpentry practices.
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.
