To convert square meters (m²) to square kilometers (km²), divide by 1,000,000. This works because 1 km = 1,000 m, so area scales as (1,000)².
Example:
25,000,000 m² ÷ 1,000,000 = 25 km²
Tip: Moving from m² to km² makes the number smaller by a factor of one million.
One square kilometer equals 1,000,000 square meters.
That’s because 1 kilometer equals 1,000 meters, and area squares the conversion: 1,000 × 1,000 = 1,000,000.
Convert square meters (m²) to square kilometers (km²) by dividing by 1,000,000:
Example: 250,000 m² ÷ 1,000,000 = 0.25 km².
Use this simple formula:
This is the same as dividing by 1,000,000.
Length units change by 1,000 from meters to kilometers.
Area uses squared units, so the factor becomes 1,000², which equals 1,000,000.
1 m² = 0.000001 km².
In scientific form, that’s 1 × 10⁻⁶ km².
10,000 m² = 0.01 km².
This is a common land size, and it converts cleanly by dividing by 1,000,000.
100,000 m² = 0.1 km².
Divide 100,000 by 1,000,000 to get 0.1.
1,000,000 m² = 1 km².
This is the direct match between the two units.
To convert square kilometers (km²) to square meters (m²), multiply by 1,000,000:
Example: 2.5 km² × 1,000,000 = 2,500,000 m².
Yes. 1 km² is the area of a square that is 1 kilometer long and 1 kilometer wide.
That same area equals 1,000,000 m².
Use square meters (m²) for smaller areas like rooms, homes, lots, and small fields.
Use square kilometers (km²) for larger areas like cities, parks, lakes, and regions.
Move the decimal 6 places to the left when converting m² to km².
