About Rai
A rai (ไร่) is the standard Thai unit of land area, defined as exactly 1,600 m² (40 m × 40 m). It is used throughout Thailand for all land measurement - from rice paddies to urban plots and national parks. Thai real estate listings always quote land area in rai, ngan (400 m² = ¼ rai), and talang wah (4 m² = 1 square wah). Thailand's total rice-paddy area is reported in millions of rai. One rai equals approximately 0.395 acres or 0.16 hectares.
About Square Yards
A square yard (yd²) is an imperial unit of area equal to a square with sides of one yard (3 ft × 3 ft or 9 ft²). It is commonly used for measuring carpet, fabric, and concrete in construction projects. A queen-size mattress covers about 5 yd², and a typical driveway might require 30-50 yd² of concrete. This unit is particularly common in the textile, carpeting, and landscaping industries in imperial-system countries.
