How it works
A rai equals 4 ngan, 400 square wa or 1,600 square metres. Choose a single unit or enter whole rai, 0–3 ngan and less than 100 square wa. Areas accept up to 6 decimal places; conversions preserve the entered precision.
Example
2 rai + 1 ngan + 50 square wa = 3,800 m² = 950 square wa = 2.375 rai.
Can I enter a title-deed area?
You can convert its area units. This does not measure boundary lines, survey a plot or value land. Check the original document. Single-unit values accept up to 9 whole digits, with non-negative input.
