Historical inertia and market familiarity. In the US, all property records, building codes, and consumer expectations use square feet. Converting would require re-recording millions of property deeds and re-educating an entire market. The UK maintains dual usage partly due to its property market's long history and American influence in luxury real estate.

Divide by 10 then subtract 7%. For example: 1,000 sq ft ÷ 10 = 100, minus 7% = 93 m². The actual answer is 92.9 m², so you're within 0.1%. For rougher estimates, just divide by 11: 1,000 ÷ 11 = 91 m² (about 2% error).

No! You cannot convert room dimensions and multiply. A 10×10 ft room is 100 sq ft = 9.29 m². But 10 ft = 3.048 m, so 3.048 × 3.048 = 9.29 m². Always calculate area first, then convert, or convert dimensions then multiply.

Different countries measure different things. US includes all internal space, while many European countries separate 'living area' from total area, excluding walls, balconies, or storage. Additionally, exchange rates and local purchasing power make direct price comparisons misleading.

US typically includes all finished, heated space including closets and hallways. Europe often uses 'net living area' excluding walls, balconies, and sometimes storage. In Asia, it varies: Hong Kong includes exterior walls and common areas in 'gross area,' while Japan's listings might exclude balconies entirely.
