When Rai and square meters are used together
Rai is the land-area unit most people encounter in Thai property listings, title-deed discussions and agricultural land descriptions. Square meters are easier to compare with building footprints, floor plans and international metric measurements. Converting between the two lets you compare a Thai land listing with dimensions or prices quoted per square meter.
The relationship is exact: 1 Rai equals 1,600 square meters. That means you do not need an approximation for this conversion; multiply the number of Rai by 1,600.

Practical example: comparing a land listing
A listing for 1.5 Rai represents 2,400 m². If the seller quotes a total price, dividing that price by 2,400 gives an approximate price per square meter. This is useful when you want to compare several plots that are advertised in different units.
For legal boundaries, ownership and surveyed dimensions, use the measurements shown on the relevant land documents or a qualified surveyor. This converter only changes area units; it does not verify a plot boundary.
Common mistakes to avoid
- Do not confuse Rai with Ngan: 1 Rai equals 4 Ngan.
- Do not treat Rai as a length measurement; Rai measures area.
- For price comparisons, make sure every listing is converted to the same area unit before comparing price per unit.
