Why the Thai system has so many units
Rai is the headline unit on most listings — about 0.4 acres or 1600 m². It subdivides into 4 ngan (400 m² each), which subdivide into 100 square wah (4 m² each).
A 50-wah townhouse plot is 200 m². A 1-rai house plot is 1600 m². If you're shown a number in just "wah", multiply by 4 to get m².
