Definition of Area

Area is a fundamental measurement in geometry that quantifies the size of a two-dimensional region or surface. It represents the amount of space enclosed by a boundary, such as the perimeter of a shape. Area is typically expressed in square units, and its magnitude depends on the shape and size of the region being measured.

Understanding area is essential for a variety of applications. For instance, when determining the amount of material needed to cover a surface, estimating land areas, calculating floor space in buildings, or assessing the size of plots, a precise measurement of area is crucial. By accurately converting between different area units, you can work seamlessly across various systems of measurement and ensure consistency in your calculations.

Units of Area

Here, we present you with a range of widely utilized units for measuring area, including metric, imperial, and other units, along with the conversion factors between them.

Metric Units

  • Kilometer² (km²) - The kilometer squared is a unit of area, which is equivalent to 1,000,000 m². It is used for measuring large areas, such as the area of a city, or country.

  • Meter² (m²) - The meter squared is a commonly used unit for measuring areas, such as area of land, houses, apartments and more. It represents the area of a square with sides measuring one meter each.

  • Centimeter² (cm²) - The centimeter squared is a smaller unit, equal to 100 mm², suitable for precise measurements, such as measuring paper sheet sizes, product packaging material, stickers and more.

  • Millimeter² (mm²) - The millimeter squared is an even smaller unit for area measurement that is commonly applied for precise measurement of components, such as electronic parts, medical implants, microorganisms and more. It is equal to 0.01 cm².

Imperial Units

  • Mile² (mi²) - The square mile is a unit commonly used in the United States for measuring large areas. It is equal to an area of 3,097,600 yd².

  • Yard² (yd²) - The square yard is equal to 9 ft². It is frequently used for measuring areas in landscaping and construction.

  • Foot² (ft²) - The square foot is a popular unit for residential and commercial property measurement that is equal to 144 in².

  • Inch² (in²) - The square inch is commonly used for smaller measurements and is equal to 1/144, or 0.0069 ft².

Other Units

  • Hectare (ha) - The hectare is widely used in agriculture and land management. It is equal to an area of 10,000 m².

  • Are (a) - The are is often used in European countries for measuring land areas that is equal to 100 m².

  • Acre (ac) - The acre is predominantly used in the United States, Canada, and the United Kingdom. It is equal to 4,840 yd².

  • Circular mil (cmil) - The circular mil is a unit of area, equal to the area of a circle with a diameter of one mil (one thousandth of an inch or 0.0254 mm). It is equivalent to *5.067 10^(-4) mm²**.

  • Circular inch (cin) - The circular inch is a unit employed in engineering and physics. It is equal to 1,000,000 cmil, or equivalent to 506.7 mm².

  • Mil² (mil²) - The square mil is a unit of area, equal to the area of a square with sides of length one mil. Since a mil is one thousandth of an inch, the square mil is equal to 0.000001 in².

  • Barn (b) - The barn is used to measure the cross-sectional area of atomic nuclei. It is approximately the cross-sectional area of a uranium nucleus, or 10^(-28) m².
