Square nanometre (nm²)
The square nanometre (symbol: nm²) is a decimal submultiple of the SI derived unit of area, the square metre. One square nanometre equals 10⁻¹⁸ square metres, representing an extremely small surface area defined by a square measuring one nanometre on each side. It is widely applied in molecular biology, materials science, and semiconductor technology to quantify atomic structures, protein cross-sections, and integrated circuit transistor features.
