Square Kilometer (km²)

Definition: A square kilometer (symbol: km²) is a multiple of the square meter, equal to the area of a square with 1 kilometer (1000 meters) on each side. One square kilometer equals 1,000,000 square meters or approximately 0.3861 square miles.

History: Developed as part of the metric system's decimal-based scaling, the square kilometer became particularly useful for geographical measurements. Its adoption grew with the metric system's international acceptance in the 19th and 20th centuries.

Current use: Primarily used to measure large land areas such as cities, national parks, and countries. Commonly appears in geographical surveys, urban planning, and environmental studies. Most world maps and atlases use square kilometers, though some US publications still use square miles.

Square Meter (m²)

Definition: A square meter (symbol: m²) is the SI derived unit of area. It is defined as the area of a square with sides measuring exactly one meter in length. This is the fundamental unit for measuring two-dimensional spaces in the metric system.

History: The square meter was introduced as part of the metric system during the French Revolution in the 1790s. Its definition has evolved with the meter's redefinitions, most recently tying it to the speed of light in 1983. As the meter was redefined, the square meter automatically adjusted while maintaining its fundamental relationship.

Current use: Used worldwide for measuring room sizes, construction areas, and land parcels in metric countries. It's the standard unit in architecture, engineering, and real estate everywhere except the United States. Even in countries that use imperial units for distance, square meters are often used for technical and scientific applications.
