About Square Yard (yd²)
Definition
The square yard is an imperial unit of area equal to the area of a square with sides of one yard (0.8361 m², or 9 square feet).
Mathematical Relationship
1 yd² = 9 ft² = 1,296 in² = 0.8361 m². 4,840 yd² = 1 acre.
Conversion Formula
To convert yd² to m²: multiply by 0.8361. To ft²: multiply by 9. To acres: divide by 4,840.
Practical Applications
Carpet and flooring purchases, fabric bolts, concrete paving, and garden area calculations.
Interesting Facts
Carpet is traditionally sold by the square yard in the US, though some retailers have switched to square feet.
Common Mistakes
Forgetting 1 yd² = 9 ft², not 3 ft². A yard is 3 ft, but area requires squaring: 3² = 9.
Educational Tips
Picture a square 3 feet on each side — that's 1 square yard (9 square feet). Great for carpet shopping math.
About Square Mile (mi²)
Definition
The square mile is an imperial unit of area equal to the area of a square with sides of one mile (2.59 km²).
Mathematical Relationship
1 mi² = 640 acres = 27,878,400 ft² = 2.59 km² = 259 ha.
Conversion Formula
To convert mi² to km²: multiply by 2.59. To acres: multiply by 640. To hectares: multiply by 259.
Practical Applications
City areas, county sizes, population density, land surveys, and geographic comparisons.
Interesting Facts
Manhattan is about 22.8 mi². The state of Texas is 268,596 mi². Rhode Island (smallest US state) is 1,214 mi².
Common Mistakes
1 mi ≈ 1.609 km, but 1 mi² ≈ 2.59 km² (not 1.609). Area conversion squares the factor.
Educational Tips
1 mi² = 640 acres. This 'section' (640 acres) is the basis of the US Public Land Survey System grid.
