Square Yard
A square yard (yd²) measures the area of a square one yard per side. It is commonly used for landscaping, fabric, and carpeting. Its mid-range scale makes it ideal for areas too small for square feet alone but too large for centimeters.
It remains useful in both US and UK contexts across consumer and professional settings.
Square Inch
A square inch (in²) is a US customary unit used for measuring small surface areas. It represents the space within a one-inch square. Square inches appear in hardware, packaging labels, and electronics, especially where compact and detailed sizing matters.
In global manufacturing, products often list both square inches and square centimeters, making conversion essential for compatibility across regions.
