About Square Millimeters
A square millimeter (mm²) is a metric unit of area equal to a square with sides of one millimeter. It is commonly used in precision engineering, electronics, and measuring very small surfaces such as microchips or printed circuit boards. To visualise: a typical pinhead has an area of about 2-3 mm². This unit is essential in microscopy, medical imaging, and manufacturing where tiny, precise measurements are critical.
About Square Nautical Miles
A square nautical mile (nmi²) equals the area of a square with sides of one nautical mile (1,852 m), giving approximately 3,429,904 m² - about 343 hectares. This unit is used in maritime and aviation contexts to describe patrol zones, territorial extents, and maritime boundaries. Exclusive Economic Zones (EEZs) and military operating areas are often quoted in square nautical miles. One square nautical mile is approximately 1.32 square statute miles.
