An acre is a unit of area commonly used in the United States and other countries that do not use the metric system. It is traditionally defined as the area of one chain by one furlong (66 by 660 feet), which is exactly equal to 10 square chains, 1/640 of a square mile, or 43,560 square feet. However, when converting an acre to metres, it is important to note that an acre does not have a fixed length and width in metres because it is a measure of area, not length.
To understand the dimensions in metres, we can convert the total area of an acre to square metres. One acre is equal to approximately 4,046.86 square metres. This means that if you were to have a square plot of land that is one acre in size, each side of the square would be approximately 63.61 metres long (since the square root of 4,046.86 is about 63.61).
However, it’s important to remember that an acre can be any shape—rectangular, circular, or irregular. As long as the total area is 4,046.86 square metres, it is considered one acre. For example, a rectangular plot of land that is 80 metres long and 50.59 metres wide would also be one acre in size (80 x 50.59 = 4,047.2 square metres).
In summary, while an acre does not have a fixed length and width in metres, it is equivalent to approximately 4,046.86 square metres. If the acre is in the shape of a square, each side would be about 63.61 metres long.
