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.
Sections
Definition
A section is a unit of area used in the US Public Land Survey System, equal to 1 square mile (640 acres or approximately 2.59 km²).
History
The section was established by the US Land Ordinance of 1785 to systematically survey and distribute public lands. The grid system divided territories into townships of 36 sections each.
Current use
Sections are still used in the United States for land descriptions, especially in rural and agricultural areas. Legal descriptions of property in the western and midwestern US frequently reference sections.
