Units Land Measurement
How is land measured in Thailand?
Land here is measured in Rai, Ngan and Wah.
1 rai = 4 ngan or 1600 sq mt
1 ngan = 100 wah or 400 sq mt
1 wah = 4 sq mt
So what does it all mean?
1 acre = 2.5 rai approx.
1 hectare = 6.25 rai approx.
The metric system of measurement is usually used in relation to the construction of buildings.
Land prices are usually expressed/quoted in Baht per Rai, or, for smaller plots Baht per Wah.
