Simple Conversion for Real Estate and Construction

A 1,500 square foot apartment in the US would be listed as about 140 square meters in Europe. Converting between these common area units is essential for international real estate, construction planning, and comparing space across different measurement systems.

Step-by-Step Conversion

Square フィート to Square メートル

  1. Find your area in square feet (e.g., 1,500 sq ft)
  2. Divide by 10.764
  3. Result: 1,500 ÷ 10.764 = 139.4 square meters

Square メートル to Square フィート

  1. Find your area in square meters (e.g., 100 sq m)
  2. Multiply by 10.764
  3. Result: 100 × 10.764 = 1,076.4 square feet

Why the Conversion Isn't Intuitive

Many people expect that since 1 foot ≈ 0.3 meters, the area conversion would be similar. But area is two-dimensional:

  • 1 foot = 0.3048 meters
  • 1 square foot = 0.3048 × 0.3048 = 0.0929 square meters
  • So 1 square meter = 10.764 square feet

The 変換係数 is squared, making 1 square meter much larger than you might expect—about the size of a small closet.

Converting Property Listings

When comparing international real estate:

US Listing (in sq ft)

"1,800 sq ft, 3 bed, 2 bath"

Convert: 1,800 ÷ 10.764 = 167 sq m

European Listing (in sq m)

"120 sq m, 3 bed, 2 bath"

Convert: 120 × 10.764 = 1,292 sq ft

Note that European listings often don't include garage space, while US listings usually do.

まとめ

Converting square feet to square meters requires dividing by 10.764 (or approximately 10 for quick estimates). A typical 1,500 sq ft home equals about 140 square meters. Remember that area 変換係数s are squared compared to length conversions, which is why the numbers differ significantly from the simple 3 feet ≈ 1 meter relationship.
