1. Understand the base relationship:
   1 Square Millimeter = 1.0E-6 m²
   1 Square Kilometer = 1000000 m²
2. Establish the conversion factor:
   1 mm2 = (1.0E-6 m²) / (1000000 m²/km2) = 1.0E-12 km2
3. Apply the conversion:
   Multiply the value in mm2 by 1.0E-12 to get the equivalent in km2

Example Conversion
