Square Kilometer [km2] to Square Meter [m2] Converter

Quick Reference

1 Square Kilometer (km2) = 1000000 Square Meter (m2)

1 Square Meter (m2) = 1.0000e-6 Square Kilometer (km2)

How to Convert Square Kilometer to Square Meter

1 km2 = 1000000 m2
1 m2 = 1.0000e-6 km2

To convert Square Kilometer to Square Meter, multiply the value by 1000000. To convert Square Meter back to Square Kilometer, divide by 1000000.

Example: convert 10 km2 to m2:
10 km2 = 10 x 1000000 = 10000000 m2

↔ Convert Square Meter to Square Kilometer

Square Kilometer

Definition: A square kilometer (km²) is a unit of area equal to a square that is 1 kilometer on each side. It is a multiple of the square meter, the SI unit of area.

History/origin: The square kilometer is derived from the kilometer, which is part of the metric system established in France in the late 18th century. The metric system was designed to be a standardized and coherent system of measurement based on decimal multiples.

Current use: Square kilometers are used to measure large areas, such as the size of cities, countries, lakes, and other geographical features. It's a common unit in geography, cartography, and environmental studies.

Square Meter

Definition: A square meter (m²) is the SI derived unit of area, equivalent to the area of a square whose sides are one meter long.

History/origin: The square meter is derived from the meter, which was originally defined in the late 18th century as one ten-millionth of the distance from the equator to the North Pole along a meridian.

Current use: Square meters are widely used for measuring the area of rooms, buildings, land, and other surfaces. It's a standard unit in real estate, construction, and many other fields.
