Square Millimeters (mm²)
Definition
A square millimeter (mm²) is a metric unit of area equal to the area of a square with sides of 1 millimeter. It equals 0.000001 square meters (10⁻⁶ m²) and is part of the International System of Units (SI).
History
The square millimeter derives from the metric system established during the French Revolution in the late 18th century. As a sub-unit of the square meter, it became widely adopted for precision measurements in engineering and manufacturing with the rise of industrialization.
Current use
Square millimeters are commonly used in engineering, electronics, and manufacturing to measure very small surfaces — such as cross-sections of wires, microchip areas, and precision mechanical parts.
Ares (a)
Definition
An are (a) is a metric unit of area equal to 100 square meters. It represents the area of a square with sides of 10 meters.
History
The are was introduced as part of the metric system in France in 1795. While officially still a recognized unit, it has largely been superseded by the hectare in most practical applications.
Current use
Ares are used primarily in some European countries for measuring small to medium land plots, gardens, and agricultural parcels. In France, Belgium, and Luxembourg, land listings sometimes reference ares.
