About Square yards and Square kilometers
Square yards (yd²): Nine square feet, or 0.836 m²; less commonly used than square feet but still appears in landscaping and some flooring. Common uses: Carpet and large-area flooring sales, athletic fields (football, soccer field dimensions), and some landscaping contexts.
Square kilometers (km²): One kilometer squared, or one million square meters. Common uses: City area, national park sizes, agricultural land, and geographic features at the regional scale.
