Square Mile [mi²]

A square mile (mi²) is a unit of area used primarily in the United States and the UK to measure large land areas. It represents a square that is one mile long on each side.

1 square mile = 2.59 square kilometers = 640 acres.

Square miles are commonly used to describe the size of cities, counties, and large geographic regions.

Square Nanometer [nm²]

A square nanometer (nm²) is a unit of area equal to a square with sides 1 nanometer long (1 nm = 1 billionth of a meter, or 10⁻⁹ m).

It’s used to measure extremely tiny areas, like the surface of molecules or nanomaterials.

1 nm² = 1 × 10⁻¹⁸ m².
