What Area Units Are Supported?

Name	Symbol	Measurement System	Description
square meter	m²	International System of Units (SI) / Metric System	A square meter is a unit of area measurement in the metric system. It is commonly used to quantify the size or extent of two-dimensional surfaces. The square meter is defined as the area of a square with sides measuring one meter in length.
square kilometer	km²	International System of Units (SI) / Metric System	A square kilometer is a unit of area measurement in the metric system. It is commonly used to quantify large areas, such as landmasses, regions, or cities. The square kilometer is defined as the area of a square with sides measuring one kilometer in length.
square centimeter	cm²	International System of Units (SI) / Metric System	A square centimeter is a unit of area measurement in the metric system. It is commonly used to quantify small areas, such as the size of objects, the surface area of materials, or the dimensions of small spaces. The square centimeter is defined as the area of a square with sides measuring one centimeter in length.
square millimeter	mm²	International System of Units (SI) / Metric System	A square millimeter is a unit of area measurement in the metric system. It is commonly used to quantify very small areas, such as the size of fine details, tiny objects, or the surface area of micro-scale components. The square millimeter is defined as the area of a square with sides measuring one millimeter in length.
square micrometer	μm²	International System of Units (SI) / Metric System	A square micrometer, also known as a square micron, is a unit of area measurement in the metric system. It is used to quantify extremely small areas, especially on the microscale or in the field of nanotechnology. The square micrometer is defined as the area of a square with sides measuring one micrometer (or one millionth of a meter) in length.
hectare	ha	Non-SI Metric	A hectare is a unit of area measurement commonly used in agriculture, land management, and urban planning. It represents a larger area than square meters or square kilometers, providing a convenient measure for quantifying land areas.
acre	ac	United States customary / Imperial system	An acre is a unit of area measurement commonly used in land-related activities, particularly in agriculture, real estate, and land management. It is primarily used in the United States, the United Kingdom, and other countries with historical ties to British systems of measurement.
square yard	yd²	United States customary / Imperial system	A square yard is a unit of area measurement commonly used in the United States and other countries that follow the imperial system of measurement. It represents a measure of area equivalent to the area of a square with sides measuring one yard (3 feet) in length.
square inch	in²	United States customary / Imperial system	A square inch is a unit of area measurement commonly used in the United States and other countries that follow the imperial system of measurement. It represents the area of a square with sides measuring one inch in length.
square foot	ft²	United States customary / Imperial system	A square foot is a unit of area measurement commonly used in the United States and other countries that follow the imperial system of measurement. It represents the area of a square with sides measuring one foot in length.
square mile	mi²	United States customary / Imperial system	A square mile is a unit of area measurement commonly used in the United States and other countries that follow the imperial system of measurement. It represents the area of a square with sides measuring one mile in length.
