About Square Centimeters
A square centimeter (cm²) is a metric unit of area equal to a square with sides of one centimeter (10 mm × 10 mm). It is widely used for measuring moderate-sized surfaces like postage stamps, credit cards, or smartphone screens. A standard credit card has an area of about 46 cm². This unit is common in everyday crafts, school science, and smaller construction projects where precision matters but square meters would be too large.
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.
