This acreage calculator helps you measure a piece of land or quickly convert between the imperial and the metric system's units for area. It can be useful when working out the total area or cost of specific materials that have to be used to cover a given plot of land. Simply provide a width and a length and you'll get an area, instantaneously. Optionally, if you provide a price per unit of area (for example how much that land costs per acre) and you'll know what the cost of the whole area is. You can also convert hectares to acres, acres to square meters, acres to square miles or pretty much any other unit of area.

  • centimeters
  • meters
  • kilometers
  • inches
  • feet
  • yards
  • miles
  • and even millimeters and nautical miles!

Other tools that can be used for similar operations are the square footage calculator and the area conversion tool.

Hectares to acres

This tool can also quickly convert hectares to acres based on the provided values. Simply click on the 'a' (acres) and from the drop-down list choose 'ha' (hectares). It's not a straightforwards operation as 1 acre equals 0.4047 hectares but results are still returned in real time. Acres are used mainly in English-speaking countries such as USA, UK, Canada or Australia but also in Jamaica, Ghana or India.

Acres to square meters

Another possible conversion is acres to square meters, it is another convenient option on the drop-down list. Simply type in your result in acres (or calculate it based on width and length in any unit). Change the unit to acres then and the result will appear. Although not as popular as acres and hectares, converting from and to square meters is still a useful tool in your belt. With this tool it becomes even easier to calculate, even if you are using the imperial system.

Acres to square miles

You might also be interested in converting acres to square miles. It can be achieved by changing a unit in the drop-down list, as with the other conversions.

The reverse operation (square miles to acres) is also possible. You can do so by simply inputting the value in miles and then changing the units to acres.
