Convert square meter to square millimetre
Square Millimetre
The square millimetre (mm²) is a unit of area in the International System of Units (SI), equal to the area of a square with sides one millimetre in length, equivalent to 10⁻⁶ square metres or 0.01 square centimetres. It is commonly used in engineering, manufacturing, and science for measuring small cross-sectional areas, such as wire gauges, material thickness, and precision components. In electrical engineering, conductor cross-sections are often specified in square millimetres. It is one of the most practical small-area metric units in technical applications.
