Square Meters to Square Kilometers (m² to km²) Converter

1 square meter (m²) = 0.000001 square kilometers (km²). To convert square meters to square kilometers, multiply by 0.000001: 80 m² × 0.000001 = 0.00008 km². Also searched as square metres to square kilometres.

1 m² = 0.000001 km²

Quick facts

How to convert square meters to square kilometers

  1. Take the value in square meters.
  2. Multiply it by 0.000001 (the number of square kilometers in one square meter).
  3. Round the result to the precision you need.
km² = m² × 0.000001

Worked example (a two-bedroom flat): 80 m² × 0.000001 = 0.00008 km².

To convert square kilometers back to square meters, multiply by 1,000,000, or divide by 0.000001.
