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.
About Square Decimeters
A square decimeter (dm²) is a metric area unit equal to 100 square centimeters (10 cm × 10 cm) or 0.01 square meters. It represents roughly the footprint of a large paperback book or a standard floor tile. While less common in everyday language than cm² or m², square decimeters appear in cooking (pan sizes), packaging design, and as a useful stepping stone in metric calculations - notably, exactly 1 liter of liquid forms a layer 1 dm² × 1 cm deep.
