Square millimeters
The square millimetre is a unit of area equal to one millionth of a square metre (10⁻⁶ m²). In engineering, cross-sectional areas of wires and cables are standardised in square millimetres — electrical cable ratings specify conductor cross-sections in mm² (e.g., 1.5 mm², 2.5 mm², 4 mm²). In materials testing, stress is calculated as force per unit area in megapascals, where the area is expressed in square millimetres.
Square yards
The square yard is a unit of area equal to exactly 0.83612736 square metres (the square of 0.9144 m). It is used in the United States for measuring carpet, flooring, and fabric quantities, where materials are priced and sold by the square yard.
