What is a Square Millimeter and a Square Yard?

The square millimeter (symbol: mm²) is a unit of area in the metric system. It represents the area of a square with sides that are each one millimeter long.

The square yard (symbol: yd², sq yd) is an imperial and US customary unit of area. It represents the area of a square with sides that are each one yard (3 feet or 36 inches) long.

Note: The Square Millimeter is part of the metric (SI) system, primarily used globally in science and trade. The Square Yard belongs to the imperial/US customary system.

History of the Square Millimeter and Square Yard

Derived from the millimeter (one-thousandth of a meter), the square millimeter arose with the metric system as a unit for measuring extremely small areas, particularly in scientific and technical fields requiring high precision.

Derived from the yard, a unit of length with origins possibly related to the human stride or arm span, the square yard became a standard area measurement in the English (and later imperial and US customary) systems. It was traditionally used for measuring textiles and smaller land areas.
