Convert Cubic Metres to Acre Feet


What is a Cubic Metre?

  • A cubic metre (m³) is a unit of volume.
  • It means a cube that is 1 meter long, 1 meter wide, and 1 meter high.
  • It is used to measure water, soil, or any material in three dimensions.

What is an Acre-Foot?

  • An acre-foot is a unit of volume commonly used in agriculture and water management.
  • It is the volume of water that would cover 1 acre of land to a depth of 1 foot.
  • It is useful when talking about irrigation water or reservoir capacity.

Why Convert Between Them?

  • Sometimes water volume is measured in cubic metres (metric system).
  • But land and water use in farming or irrigation may be measured in acre-feet (imperial system).
  • Converting helps understand how much water is available or needed per acre.

Conversion Factor

1 acre-foot = 1233.48 cubic metres

So,

Acre-feet=Cubic metres/1233.48

Example Calculation

If you have 2467 cubic metres of water, to find how many acre-feet that is:

Acre-feet=2467/1233.48≈2 acre-feet

Summary for the Farmer

  • To get acre-feet from cubic metres, divide the cubic metres by 1233.48.
  • This tells you how many acres can be covered with water 1 foot deep.
  • Useful for planning irrigation or managing water supplies.
