# Acre-Foot
An acre-foot (symbol: ac-ft) is the standard unit of volume used in American water resource management and reservoir engineering.
- 1 Acre-Foot = 325,851.4 U.S. gallons
- 1 Acre-Foot = 43,560 cubic feet
- 1 Acre-Foot = 1,233.5 cubic meters
As a practical rule of thumb in US municipal hydrology, one acre-foot provides enough water to satisfy the annual indoor and outdoor water consumption of two to three typical single-family households.
A volumetric water unit representing the amount of water required to cover one acre of land to a depth of one foot.
