# Area conversion

Units of area are typically expressed as the product of two length units. Some common units of area include:

- Square meter (m²): the area of a square with sides of one meter
- Square kilometer (km²): the area of a square with sides of one kilometer
- Square centimeter (cm²): the area of a square with sides of one centimeter
- Square millimeter (mm²): the area of a square with sides of one millimeter
- Square foot (ft²): the area of a square with sides of one foot
- Square yard (yd²): the area of a square with sides of one yard
- Acre (ac): a unit of area commonly used in land measurement, equivalent to 43 560 square feet or approximately 4 047 square meters
- Hectare (ha): a unit of area commonly used in land measurement, equivalent to 10 000 square meters or approximately 2.47 acres

Here are some units of area: square meter, square kilometer, square centimeter, square millimeter, square foot, square yard, acre, hectare, square inch.

Converting area units is the process of expressing an area measurement in one unit of area to another unit of area. The conversion process involves multiplying or dividing the original value by a conversion factor that relates the two units of area. For example, to convert square meters (m²) to square feet (ft²), you would multiply the value in square meters by 10.7639, which is the conversion factor between these two units.

In geometry, the area is the measurement of the size of a two-dimensional region enclosed by a closed figure. It is a quantitative representation of how much space a flat surface takes up, typically measured in square units. The formula for finding the area of a shape depends on its geometric properties. For example, the area of a rectangle can be found by multiplying its length and width, while the area of a circle can be found by multiplying pi by the radius squared.

The units of area depend on the system of measurement being used. In the International System of Units (SI), the standard unit of area is the square meter (m²), while in the United States customary system, the standard unit of area is the square foot (ft²). The area of a shape is always non-negative. This means that it is impossible for a shape to have a negative area. The concept of area is closely related to the concept of perimeter, which is the distance around the boundary of a two-dimensional shape.
