About Square Feet
A square foot (ft²) is an imperial unit of area equal to a square with sides of one foot (12 in × 12 in or 144 in²). It is the standard for measuring floor space in the United States and some other countries. A typical bedroom is 100-150 ft², and the average American house is roughly 2,000-2,500 ft². This unit dominates real estate listings, flooring sales, and construction in countries using imperial measurements.
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.
