  • A square centimeter is a metric unit of area equal to a square with sides measuring one centimeter in length. It is commonly used in everyday measurements and in scientific contexts for smaller areas.

  • The square meter is the SI derived unit of area, used to measure the size of an area. It is defined as the area of a square whose sides measure exactly one meter in length.

  • A square kilometer is a metric unit of area equal to the area of a square with sides that are one kilometer long. It is commonly used to measure large geographical areas like cities or countries.

  • An are is a metric unit of area equal to 100 square meters. Not commonly used in everyday conversation, it is more prevalent in land measurement in some countries.

  • A hectare is a metric unit of area defined as 10,000 square meters. It is commonly used in agriculture and forestry to measure large plots of land.

  • A square inch is a unit of area in the Imperial and U.S. customary measurement systems. It is the area of a square with each side measuring one inch.
