What is an Acre-Inch?

An acre-inch is a unit of volume commonly used in agriculture to measure the amount of water applied to a field. It represents the volume of water that would cover one acre of land to a depth of one inch. This unit is particularly useful for irrigation planning and water management, as it helps farmers and water resource managers quantify the amount of water needed for crops over a given area. One acre-inch is equivalent to approximately 27,154 gallons of water.

How to Calculate Acre-Inch to Gallons?
