Acre Feet Formula:
| From: | To: |
The acre-foot is a unit of volume commonly used in the United States in reference to large-scale water resources, such as reservoirs, aqueducts, canals, and river flows. It is defined as the volume of one acre of surface area to a depth of one foot.
The calculator uses the acre feet formula:
Where:
Explanation: This calculation converts the volume from cubic feet to acre-feet by dividing by the number of square feet in one acre.
Details: Acre-feet is particularly important in water management, irrigation planning, and reservoir capacity measurement. It helps quantify large volumes of water for agricultural, municipal, and environmental applications.
Tips: Enter the area in square feet and the depth in feet. Both values must be positive numbers. The calculator will automatically compute the volume in acre-feet.
Q1: Why is 43,560 used in the calculation?
A: 43,560 is the number of square feet in one acre, which is the standard conversion factor for area measurements.
Q2: What are common applications of acre-feet measurements?
A: Acre-feet is commonly used to measure water volume in reservoirs, irrigation systems, and water rights allocations.
Q3: How does acre-feet relate to other volume measurements?
A: One acre-foot equals approximately 325,851 gallons, 1,233 cubic meters, or 43,560 cubic feet.
Q4: Can this calculator be used for any shape area?
A: Yes, as long as you know the total area in square feet and the uniform depth, this calculation works for any shape.
Q5: Is acre-foot used outside the United States?
A: While primarily used in the US, the acre-foot is sometimes referenced in international water management discussions, though metric units are more common globally.
