Metric Units:

Square Metres (m²): The base unit of area in the metric system. It represents the area of a square with sides of one meter. They are widely used in most countries for measuring land, rooms, and other surfaces.
Square Nanometres (nm²): A tiny area unit equal to one billionth of a square meter. It is typically used in scientific fields like nanotechnology.
Square Micrometres (µm²): Also known as a micron, this unit is one-millionth square meter, and it is used in fields like biology and materials science to measure very small areas.
Square Millimetres (mm²): A smaller metric unit used for precise measurements, especially in engineering, machining, and manufacturing.
Square Centimetres (cm²): A standard unit in the metric system, equal to one-hundredth of a square meter. It is used to measure smaller surfaces like the area of papers or small objects.
Square Decimetres (dm²): A unit equal to one-tenth of a square meter is used for medium-sized areas.
Square Decimetres (dam²): Larger than square meters, this unit is occasionally used to measure larger areas, such as small plots of land.
Square Kilometres (hm²): This unit is equal to 10,000 square meters and is typically used to measure large plots of land.
Square Kilometres (km²): A unit of area used to measure large tracts of land, such as cities or geographical regions. One square kilometre is equal to 1,000,000 square meters.
Hectares (ha): A metric unit commonly used to measure large land areas, especially agriculture. One hectare is equivalent to 10,000 square meters (or 100 acres).
Decares (daa): A unit equal to 1,000 square meters or 0.1 hectares commonly used for measuring land in some countries.
Ares (a): A unit equal to 100 square meters. Ares are frequently used in agriculture and land measurement, especially for small plots of land.
Centiares (ca): A unit of area equal to one square meter (1 m²). This unit is rarely used, but when it is, it's mostly in land measurements.

Imperial and U.S. Customary Units:

Square Feet (ft²): A widely used unit of area in the imperial system, particularly in the United States. It represents the area of a square with sides of one foot. It is commonly used to measure the size of rooms, houses, and plots of land.
Square Inches (in²): A small unit of area used primarily in the United States to measure surfaces such as screens, small objects, or papers. It represents the area of a square with sides of one inch.
Square Yards (yd²): A larger unit than square feet used to measure more substantial areas such as backyards or fabric. One square yard is equivalent to nine square feet.
Square Miles (mi²): A large area unit used to measure large tracts of land, such as cities, counties, and entire countries. One square mile is equal to 640 acres.
Acres (ac): A commonly used unit in the U.S. and the U.K. for measuring land, particularly agricultural land. One acre equals 43,560 square feet or about 4047 square meters.
Square Rods (rd²): Also known as a perch, this is a historical unit of area used primarily in the U.S. and U.K. It is mainly used in land surveying; one square rod equals 30.25 square yards.
Square Chains (ch²): The square chain is another historical unit used in land surveying, particularly for measuring large plots of land. One square chain equals 43,560 square feet (exactly one acre).
U.S. Survey Square Feet (ft²) U.S. Survey: A variation of the square foot used in the U.S. for official land surveys. It is very similar to the standard square foot but differs slightly due to historical adjustments in the survey system.

French Units (Quebec):

Square French Feet (fr.ft²) (Quebec): This is a traditional unit of area used in Quebec. It is based on old French land measurements and is still occasionally referenced in historical documents or older land deeds.
Arpents (a²) (Quebec): A historical unit of area used in Quebec and parts of France. It is still occasionally used in rural Quebec's real estate and land transactions. One arpent is approximately equal to 34,191 square feet or about 3,420 square meters.
Perches (p²) (Quebec): A perch is a small, traditional unit used in old French land surveys. It was historically used to measure smaller land plots or building surfaces.

These units cover a variety of area units, ranging from commonly used modern units to historical or region-specific units that are still relevant in specialized contexts.
