Square meters to square kilometers Conversion
1 square meters (meters²) is equal to 0.000001 square kilometers (km²).
1 meters² = 0.000001 km²
or
1 km² = 1000000 meters²
Formula
To convert a area from square meters (meters²) to square kilometers (km²), divide the area in square meters by 1000000
a(km²) = a(meters²) / 1000000
Examples:
Convert 100 square meters to square kilometers:
a(km²) = 100meters² / 1000000 = 0.0001 km²
