About These Units
- Square Kilometers (km²)
- The area of a square 1 km on each side, exactly 1,000,000 m² or 100 hectares. It is used for the areas of countries, cities, lakes, and wildfires, and equals about 0.386 square miles.
- Square Centimeters (cm²)
- The area of a square 1 cm on each side, or one ten-thousandth of a square meter. It is used for small surfaces such as burns and wounds in medicine, and for cross-sections in school physics problems.
