To convert square miles (mi²) to square meters (m²), use a single fixed factor.
Example:
For a quick estimate, you can round the factor to 1 mi² ≈ 2.59 million m², but use the full number when you need more exact area conversion from square miles to square meters.
1 square mile equals 2,589,988.110336 square meters.
This value comes from the exact definition of a mile in meters.
Use this formula:
square meters = square miles × 2,589,988.110336
It works for any area size, from small land plots to large regions.
Multiply the number of square miles by 2,589,988.110336.
Example: 3 sq mi × 2,589,988.110336 = 7,769,964.331008 sq m
Area units scale by squares, not by length.
A mile is much longer than a meter, so a square mile covers millions of square meters.
The conversion uses exact base definitions: 1 mile = 1,609.344 meters.
Squaring that length gives 1 sq mi = 2,589,988.110336 sq m.
The steps stay the same for land area:
This is common for maps, property totals, and region size.
0.5 square mile = 1,294,994.055168 square meters
That’s half of 2,589,988.110336 sq m.
Common rounding options:
A quick estimate works like this:
1 sq mi ≈ 2.59 million sq m
For example, 10 sq mi ≈ 25.9 million sq m.
Use the exact factor when you need accurate results.
Both measure area, but they fit different scales.
Square meters (m²) suit buildings and small sites. Square miles (sq mi) suit cities, counties, and large land areas.
Find the area in square miles first, then convert:
This avoids mixing units during the first step.
No. The area stays the same.
Only the unit changes, from square miles to square meters.
Keep more digits during the math, then round at the end.
Use 2,589,988.110336 as the conversion factor for the best accuracy.
A square meter is very small compared to a square mile:
1 sq m = 0.0000003861021585424458 sq mi (approx.)
This is the inverse of the square mile to square meter conversion factor.
