Thai land measurements are a bit different from European, UK, or US measurements.
In Thailand, the size of land is expressed in rai , ngan and square wah (or talang wah). - One wah equals 2 metres, and thus one square wah (2X2 metres) equals 4 square metres. - One ngan is 100 square wah (400 sqm) - And one rai, the biggest unit, is 4 ngan, 400 sqw, or 1600 sqm.
Land size is usually shown in the following way : rai - ngan - sqw So If you see a sign that says ; "Land for sale 1-3-20", or similar, that means that the land is : - 1 rai - 3 ngan - and 20 sqw Or in sqm : 1600 + 3X400 + 20X4 = 2880 square meters
What does that mean in real life?
You can express the size of land in square meters, rai, acre, or any other unit, but for some it is difficult to visualize these numbers.
The drawing to the right compares these numbers to recognizable items, such as a house, a tennis court or a football field...
The table underneath compares some of the most commonly used measurements units to each other.
