Convert Square Yard to Square Mile (yd² → mi²)

Converting square yards to square miles is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in square yards

   Start with the number of square yards (yd²) you want to convert.
2. 2
   Multiply by 3.228e-7

   The conversion factor from yd² to mi² is 3.228e-7. Multiply your value by this number.
3. 3
   Read the result in square miles

   The result is your value in square miles (mi²).

Multiply the value in square yards by 3.228e-7. For the reverse direction, multiply by 3,097,600.

• ✓1 yd² = 9 ft² = 0.8361 m².
• ✓1 m² = 1.196 yd² — a square metre is slightly larger than a square yard.
• ✓Carpet rolls often come 12 ft wide — calculate yd² based on room length.

• ✗Conflating yd² with yd — different units.
• ✗Using yd² in metric architectural plans — stick to m².
• ✗Ordering too little carpet by miscalculating offcuts.

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.

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.
