How to Convert Room Dimensions (Step by Step)

  1. Measure length in feet and width in feet
  2. Multiply: ft² = length (ft) × width (ft)
  3. Convert: m² = ft² × 0.0929

Example: Bedroom 14 ft × 11 ft

14 × 11 = 154 ft². Then 154 × 0.0929 = 14.31 m².

Example: House 2,200 ft²

2,200 × 0.0929 = 204.4 m². Or mentally: 2,200 ÷ 10 = 220, then subtract 7% → 220 − 15.4 ≈ 204 m².

Why Different Countries Use Different Units

Square feet remain dominant in the US, Canada (mixed), and UK property markets. Square meters are standard in the EU, Australia, and most of the world. When comparing international real estate, always convert — European listings in m² often look small until you convert: a 75 m² Paris flat = 807 ft², which is a solid 1-bedroom by US standards.
