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 Centimeters
A square centimeter (cm²) is a metric unit of area equal to a square with sides of one centimeter (10 mm × 10 mm). It is widely used for measuring moderate-sized surfaces like postage stamps, credit cards, or smartphone screens. A standard credit card has an area of about 46 cm². This unit is common in everyday crafts, school science, and smaller construction projects where precision matters but square meters would be too large.
