An "are" (symbol: a) is a unit of area that is not part of the International System of Units (SI) but is used in some countries, particularly in Europe, for measuring land areas. One are is equal to 100 square meters (m²).
To put it simply, 1 are is equivalent to a square with sides that each measure 10 meters. It is a relatively convenient unit for measuring smaller land areas, such as gardens, small fields, or land plots, where using square meters might result in large numbers.
Here are some additional conversions to provide context:
For example, if you have a piece of land that is 5 ares in size, it would be equivalent to 500 square meters (5 ares * 100 m²/are = 500 m²).
A square centimeter (often abbreviated as cm²) is a unit of area in the International System of Units (SI). It represents a square with sides that each measure 1 centimeter (cm) in length.
One square centimeter is equal to 0.0001 square meters (m²) because there are 100 centimeters in a meter, and when you square that length, you get 0.01 square meters.
To visualize the size of a square centimeter, you can imagine a tiny square with sides that are each 1 centimeter long. It is a small unit of area and is often used for measurements of small objects or details, especially in scientific and engineering contexts.
