# How big is an acre? Explained

Article Category: Units  |

Today we're going to look at the acre - a unit of area commonly used for measuring tracts of land.

Let me begin with a question. Did you know that during the Middle Ages, an acre was defined as the amount of land ploughable in one day by one man and an ox? Not very specific, then - especially if your ox is feeling particularly lethargic. Thankfully, these days the acre unit is more clearly defined.

Ox at the ready, let's take a look at the task at hand. Perhaps you're considering purchasing a new property attached to several acres of land and you're wondering how big it is?

Or maybe you're studying for an exam and want to know how to convert square feet to acres or acres to square meters, hectares or other units of area? Well, look no further, The Calculator Site is here to help with some facts and a handy acre conversion tool.

## An acre equates to the following:

• 4046.86 square meters
• 4840 square yards
• 43,560 square feet
• 0.404686 hectares

It is important to realise that an acre can be measured in any shape - from rectangles to circles or even hexagons - so long as the total area of land is 43,560 square feet.

The most common shape for an acre is 1 furlong by 1 chain, or 660 feet by 66 feet. (source: Infoplease)

If you're struggling to get your head around just how big that area actually is, try visualising 60% of a soccer pitch, 75% of an American football field or 16 tennis courts in a 4x4 formation. If that doesn't help, consider a car park containing 150 cars parked in a square.

In case you are wondering, FIFA states that the optimal size of a soccer pitch is between 69,000 and 86,000 square feet. An American football field commonly measures around 57,564 square feet (source).

Of course, if you want an exact measurement conversion for land acreage then this handy conversion tool will help you...
