Note: This to update you that Thailand does not have an Imperial or Metric measurement system. Land size conversion can be a little confusing measure of land in Thailand is expressed in rai, ngan and square wah (or tarang wah)

• Rai - large Land measure unit
• Ngan - not so common unit
• Tarang Wa (sqwah) – use for Land & house in the Town
• 1 Rai = 4 Ngan = 400 Tarang Wa (sqwah) = 1600 Sqm
• 1 Ngan = 100 Tarang Wa (sqwah) = 1/4 Rai = 400 Sqm
• 1 Tarang Wa(sqwah) = 1/100 Ngan = 1/400 Rai = 4 Sqm
• Land size is usually shown in the following way: rai - ngan – sqwah
• So, if you see a sign "Land for sale 4-2-89", it means 4 rai, 2 ngan, 89 sqwah
• 4-2-89 = 1889 sqwah
• 4-2-89 = 7556 sqm
• 4-2-89 = 81332.11 sqf
