Convert Acre Feet to Cubic Metres


What is an Acre-Foot?

  • An acre-foot is a unit of volume commonly used in agriculture and water management.
  • It represents the volume of water that would cover one acre of land to a depth of one foot.
  • One acre is about 43,560 square feet, so one acre-foot equals 43,560 cubic feet of water.

Why Convert Acre-Feet to Cubic Meters?

  • Cubic meters (m³) is the standard unit of volume in the metric system.
  • Many irrigation systems, water usage reports, and scientific measurements use cubic meters.
  • Converting acre-feet to cubic meters helps understand water volumes in metric terms.

Conversion Formula

  • 1 cubic foot = 0.0283168 cubic meters
  • Therefore, 1 acre-foot=43,560 ft3×0.0283168 m3/ft3=1233.48 m3

How to Use the Calculator

  1. Enter the volume in acre-feet (for example, 5 acre-feet).
  2. Press “Convert”.
  3. The calculator will show the equivalent volume in cubic meters.

Example

  • Input: 5 acre-feet
  • Calculation: 5×1233.48=6167.4 cubic meters.
  • Output: 6167.4 cubic meters.

This helps you easily understand how much water you have or need in cubic meters, which can be useful for irrigation planning, water supply management, or reporting.
