What Is a Square Kilometer?

A square kilometer is a unit used to measure area.

The square kilometer, or square kilometre, is a multiple of the square meter, which is the SI derived unit for area. In the metric system, "kilo" is the prefix for thousands, or 103. A square kilometer is sometimes also referred to as a square km. Square kilometers can be abbreviated as sq km, and are also sometimes abbreviated as km². For example, 1 square kilometer can be written as 1 sq km or 1 km².

You can use an area calculator to find the area of a space in square kilometers given the dimensions.

How Much Is a Square Kilometer?

One square kilometer is equivalent to the area of a square with sides that are each 1 kilometer in length. One square kilometer is equal to 0.386102 square miles or 1,000,000 square meters.

How to Convert Square Kilometers

To convert square kilometers to another unit of area, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for square kilometers in the conversion table below.

Then, multiply the area measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

square kilometers × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
