Confusing square miles with statute miles (length).
Using 2.5 km² shortcut — correct 2.59 km² differs by 3.5%.
Mixing nautical square miles (irregular) with statute square miles.

About Square Mile and Square Yard

What is the Square Mile?

The square mile equals exactly 2.589988110336 square kilometers (or 640 acres) and is the American unit for measuring large geographic areas: counties, states, watersheds, and large parks. The continental United States covers about 3 million square miles, and Texas alone is 268,597 mi². Population density in US contexts is given in people per square mile (e.g., New York City has about 27,000 people/mi²). The square mile relates to the acre (640 acres = 1 mi²), the square kilometer (1 mi² ≈ 2.59 km²), the square foot (1 mi² = 27,878,400 ft²), and the hectare (1 mi² ≈ 259 ha). It is the natural large-area unit for American geographic discussion, though metric countries use square kilometers for the same purpose.

Real-world examples

New York City is 302.6 mi². Texas is 268,597 mi². Greater London is 607 mi².

What is the Square Yard?

The square yard equals exactly 0.83612736 square meters (or 9 square feet) and is used for American and British carpet, fabric, landscaping, and small construction projects. Carpet pricing in the US has historically been per square yard, though many retailers now also quote per square foot. Lawn-fertilizer applications and grass-seed coverage often specify rates per 1,000 yd². The square yard relates to the square foot (9 ft² = 1 yd²), the square meter (1 yd² ≈ 0.836 m²), and the acre (4,840 yd² = 1 acre). Despite the prevalence of square feet in real estate and construction, the square yard remains entrenched in textile and landscaping commerce. A typical bedroom carpet is 12–20 square yards.
