Acre: A Unit of Area
An acre is a unit of area that is commonly used for measuring land in the United States and the United Kingdom. It is equal to 43,560 square feet, or 4,840 square yards, or about 4,047 square meters, or 0.4047 hectares. The acre is defined as the area of a rectangle that has a length of one chain (66 feet) and a width of one furlong (660 feet). This is equivalent to 10 square chains, or 1/640 of a square mile.
The acre is not a standard unit in the International System of Units (SI), but it is legally recognized in some countries as a supplementary unit that can be used for trade if given as additional information and not used for land registration.
History of the Acre
The word acre comes from the Old English word aecer, which means “field” or “open land”. It is related to the Latin word ager, which also means “field”.
The acre was originally a measure of the amount of land that could be plowed by one man with a team of eight oxen in one day. This varied depending on the soil quality and the type of plow used, but it was generally around 40 rods (660 feet) long and four rods (66 feet) wide.
The acre was used as a common measure of land area in many countries in Europe and the British Isles since the Middle Ages. It was standardized by King Edward I of England in 1305 as 4,840 square yards. However, there were also different regional variants of the acre that ranged from 0.19 to 0.911 hectare.
The acre was brought to North America by the British colonists and became the standard unit of land measurement in the United States and Canada. In 1959, the international yard and pound agreement defined the international yard as exactly 0.9144 meter, which made the international acre exactly 4,046.8564224 square meters. However, the United States decided to keep using the US survey foot (and thus the US survey acre) for some purposes, which differs from the international foot by only four parts per million.
How to Convert Acre to Other Units
To convert an acre to other units of area, we can use the following conversion factors:
To convert from other units to an acre, we can use the inverse of these conversion factors.
For example, to convert 10 hectares to acres, we can use:
10 hectares x (1 acre / 0.4047 hectare) = 24.71 acres
Where Acre is Used
The acre is still widely used in the United States and the United Kingdom for measuring land area, especially for real estate, agriculture, forestry, and environmental planning. It is also used in some other countries that have historical ties with Britain, such as India, Pakistan, Bangladesh, Sri Lanka, Nepal, Jamaica, Ghana, Liberia, and The Bahamas.

Square Yard: A Unit of Area
Definition of the Square Yard
A square yard is a unit of area that measures the size of a surface. It is defined as the area of a square whose sides are one yard long. A square yard is equal to 9 square feet, 1296 square inches, or 0.836127 square meters. It is also a common unit of area in the United States customary system and the imperial system.
How to Convert Square Yard to Other Units
To convert a square yard to other units of area, we need to multiply or divide by a conversion factor. A conversion factor is a number that relates two units of measurement. For example, to convert a square yard to a square meter, we need to multiply by 0.836127, which is the conversion factor between these two units. Here are some common conversion factors for square yard and other units of area:
Where Square Yard is Used
The square yard is widely used in the United States, the United Kingdom, and some other countries as a standard unit of area measurement. It is used for various purposes, such as measuring the size of carpets, fabrics, lawns, gardens, sports fields, and more. Different countries may have different preferences or regulations for using the square yard or other units of area in different applications. Here are some examples:
History of Square Yard
The concept of measuring area by using squares dates back to ancient times. The ancient Egyptians, Babylonians, Greeks, and Romans all used different units of area based on squares with different side lengths. For example, the ancient Egyptians used a unit called setat, which was equal to a square with sides of 100 cubits (about 52 meters). The ancient Greeks used a unit called plethron, which was equal to a square with sides of 100 feet (about 30 meters). The ancient Romans used a unit called iugerum, which was equal to a square with sides of 120 feet (about 35 meters).
The modern definition of the square yard was established in the late 18th century by the British Parliament as part of the imperial system. The imperial system was designed to create a uniform and consistent system of measurement based on traditional units that were widely used in Britain and its colonies. The original definition of the yard was derived from an iron rod that was kept in London as a standard measure. The original definition of the square yard was then derived from this definition as the area of a square whose sides are one yard long.
The definition of the yard has been revised several times over the years to improve its accuracy and precision. The current definition of the yard was adopted in 1959 by an international agreement as “the length equal to 0.9144 meter exactly”. The current definition of the square yard is then derived from this definition as before.
