All title deeds in Thailand show measurements using the Thai system and are also written in Thai with Thai numerals.
The basic measurement for land is the Wah which is equal to a length of 2 meters.
One Square Wah which is also known as a Talangwah measures 2 meters x 2 meters or 4 Square meters.
Most houses in housing developments are built on lots of between 60 to 100 Square Wah or Talangwah – except the Hollywood Estate where plots are much larger than that.
So a lot sized 80 Talangwah is 320 Square Meters.
Larger parcels of land have other names, 100 Talangwah equals 1 Ngan. 4 Ngan equals 1 Rai which contains 1600 Square Meters.
For those more familiar with the old English measurement system, 1 Acre equals about 2.5 Rai, so one Rai equals about 0.4 Acres and 1 Ngan (100 Talangwah) equals about 0.1 Acres.
