Square Wah versus square meters
Square Wah is a traditional Thai area unit commonly seen with residential land, while square meters are the standard metric area unit. Converting Square Wah to m² is helpful when comparing a Thai plot with building plans, international listings or construction measurements.
The conversion is exact: 1 Square Wah equals 4 square meters. A plot of 50 Square Wah is therefore 200 m², while 100 Square Wah is 400 m² or 1 Ngan.

Example: estimating usable plot area
If a residential plot is advertised as 72 Square Wah, the land area is 288 m². That does not mean a building can necessarily cover all 288 m²; setbacks, zoning, access and other rules are separate questions.
The conversion is still useful as a first step because many plans and construction dimensions are expressed in meters rather than Square Wah.
Do not confuse Wah with Square Wah
- Wah measures length; Square Wah measures area.
- You cannot convert a linear Wah value to m² without knowing a second dimension.
- To convert Square Wah to m², multiply by 4; to convert m² to Square Wah, divide by 4.
