Square meters (m²) are units of measurement for rather large areas and square kilometers (km²) for very large areas. The conversion is made using a factor of 1,000,000, which means that 1 km² is converted to 1,000,000 m² (or 100 hectares).

How do you convert square meters to square kilometers?

Converting square meters to square kilometers is relatively simple. One square kilometer is equal to 1,000,000 square meters. So to convert a value in square meters to a value in square kilometers, you have to divide the value by 1,000,000.

Example: You want to know how many square kilometers a piece of forest with an area of 500,000 m² has.

Step 1: Divide the area of the woodland by 1,000,000. 500,000 m² ÷ 1,000,000 = 0.5 km²

Step 2: Round the result to the desired number of decimal places. In this example, we round to two decimal places. 0.5 km² (rounded to 2 decimal places)

The woodland therefore has an area of 0.5 square kilometers.
