1. What is Acre-Feet to Gallons Conversion?

The acre-foot to gallons conversion is used to convert between two common units of volume measurement, particularly in water resource management and agricultural applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• 1 acre-foot = 325,851 gallons (US)
• 1 acre-foot is the volume of water that would cover 1 acre to a depth of 1 foot

Explanation: This conversion factor is based on the US customary units where 1 acre = 43,560 square feet and 1 cubic foot = 7.48052 gallons.

3. Importance of Volume Conversion

Details: Accurate conversion between acre-feet and gallons is essential for water resource planning, irrigation calculations, reservoir capacity measurements, and water rights allocations.

4. Using the Calculator

Tips: Enter the volume in acre-feet (must be a positive number). The calculator will instantly provide the equivalent volume in gallons.
