Square Kilometer
A square kilometer (km²) is a large metric unit used to measure wide geographic areas. One km² equals one million square meters, making it perfect for cities, forests, lakes, and regions. It is widely used in maps, environmental studies, and land-use planning.
This scale helps governments, scientists, and researchers describe the size of natural and urban spaces with clarity. Converting km² into acres or square miles provides helpful context across measurement systems.
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.
