Some sites use the metric system. The area of the buildings is converted from meters to feet and then rounded.
\n\n1 square feet = 0.09290304 square meters
\n\n
5, 12, 7 - sites with metric system. And whats wrong with 1?

Most buildings are in square meters and only two clearly indicate otherwise.
