Units Land Measurement

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 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.
