About this
Scaling from a millimeter up to a kilometer is a million-to-one linear jump. When dealing with area, that jump becomes exponential. Squaring 1,000,000 results in one trillion (1,000,000,000,000). Thus, you must divide your square millimeter measurement by one trillion to effectively translate it into a single geographic square kilometer.
