Thailand has its very own units of measurements when dealing with land, which can be a little confusing at first. The units you will come across most often are talang wah and rai. Talang means squared, so 1 talang mett is 1 sqm. Metric units are used when dealing with buildings.
Thai to Metric
- 1 Wah = 2 m
- 1 Talang Wah = 4 sqm
- 1 Rai = 1600 sqm
- 1 Rai = 400 Talang Wah
- 1 Rai = 0.40 Acre (approx.)
- 1 Rai = 0.16 Hectare
- 1 Ngan = 100 Talang Wah
Metric to Thai
- 1 m = 0.5 Wah
- 1 sqm = 0.25 Talang Wah
- 1 Acre = 2.53 Rai
- 1 Hectare = 6.25 Rai
It’s not much different to back home – just a few terminology differences. Time to get the calculator out!
