Square meters to Square kilometers Converter

1 square meter (m²) equals 0.000001 square kilometers (km²).

Quick answer

  • 1 square meter = 0.000001 square kilometers
  • 1 square kilometer = 1,000,000 square meters
  • Formula: km² = m² × 0.000001

1 square meter = 0.000001 square kilometers

How to convert square meters to square kilometers

km² = m² × 0.000001

To convert square meters to square kilometers, multiply the number of square meters by 0.000001.

Example: 42 m² to km²

  1. Start with the value in square meters: 42 m².
  2. Multiply by 0.000001: 42 × 0.000001 = 0.000042.
  3. Result: 42 square meters = 0.000042 square kilometers.

Going the other way, 1 square kilometer = 1,000,000 square meters, so to convert square kilometers back to square meters you divide by the same number. See square kilometers to square meters.
