Understanding the Acres

Acre is a unit of area commonly used for measuring the area of land. The international symbol for acre is ac. It should not be confused with hectare which is also a unit of area.

It’s been used since middle or medieval ages and is still used in Commonwealth countries. For example Canada, the Cayman Islands, Ghana and India.

The formula:
Area in acres * 43560

Where do you need it in daily life?

It is commonly used in United States and a few Commonwealth countries.

It is mostly used to describe the area of large lands such as Industrial or Commercial estate, Farms, Pastures and forests. Specially, where the legal document for the sell or purchase of the land needs to define the area of land.

You can also use it to identify the cost of materials required for the purpose of landscaping and / or paving the land.

The usage of acre is not permitted in United Kingdom as a legal or formal unit of area. It’s replaced by hectare. Although it is still informally used in United Kingdom.
