Centimeter [cm2] to Square Kilometer [km2] Converter

Quick Reference

1 Centimeter (cm2) = 1.0000e-10 Square Kilometer (km2)

1 Square Kilometer (km2) = 1.0000e+10 Centimeter (cm2)

How to Convert Centimeter to Square Kilometer

1 cm2 = 1.0000e-10 km2
1 km2 = 1.0000e+10 cm2

To convert Centimeter to Square Kilometer, divide the value by 1.0000e+10 (equivalently, multiply by 1.0000e-10). To convert Square Kilometer back to Centimeter, multiply by 1.0000e+10.

Example: convert 10 cm2 to km2:
10 cm2 = 10 x 1.0000e-10 = 1.0000e-9 km2

↔ Convert Square Kilometer to Centimeter

Centimeter

Definition: A square centimeter (cm²) is a unit of area equal to a square that is 1 centimeter on each side. It is a decimal multiple of the square meter, the SI unit of area.

History/origin: The square centimeter is derived from the centimeter, 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 centimeters are commonly used to measure smaller areas, such as the surface area of small objects, diagrams, or cross-sections. They are frequently used in scientific and technical contexts where metric units are preferred.

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.
