# Rais

A rai (Thai: ไร่) is a unit of area, equal to 1 square sen (เส้น) or 1,600 square meters (40m × 40m), and is used in measuring land area for a cadastre or cadastral map. Its current size is precisely derived from the meter, but is neither part of nor recognized by the modern metric system, the International System (SI). The rai equals four ngaan (Thai: งาน) or 400 square wa (Thai: ตารางวา). The rai equals 0.3954 acres.
