About Homesteads
A homestead is a land area unit of exactly 160 acres (approximately 64.75 hectares or 0.6475 km²) - one quarter of a one-square-mile section - established by the US Homestead Act of 1862. The Act promised 160 acres to settlers willing to farm the land for five years, transforming the American West: over 270 million acres (about 10% of the entire continental US) were granted to 1.6 million homesteaders. In the US Public Land Survey System, one homestead equals a quarter-section, with four homesteads forming one full section of 640 acres.
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.
