How the calculation works
Converting square metres to rai means dividing by 1,600, since large holdings — industrial estate land, development sites — are often recorded in square metres from the start. Converting back to rai makes it possible to compare directly against other plots quoted the way the Thai market usually quotes them.
Example: a 24,000 square-metre plot is exactly 15 rai. When the result doesn't land on a round number — say, 24,500 square metres — the tool shows both the decimal rai figure and the equivalent rai-ngan-wah breakdown side by side.

Frequently asked questions
How many square metres make up one rai?
1,600 square metres equal 1 rai.
How many rai is 10,000 square metres?
10,000 square metres equals 6.25 rai — the same as exactly 1 hectare.
What if the result doesn't land on a whole rai?
The tool shows the decimal rai figure and automatically breaks it down into rai-ngan-wah, so it matches the format used on a title deed.
