Frequently asked questions
How many square metres are in 1 rai?
One rai equals 1,600 square metres. It is also 4 ngan or 400 square wah, since 1 ngan is 400 square metres and 1 square wah is 4 square metres. Enter 1 rai in the Thai land tab to see it in every unit at once.
How do I convert rai to ngan and square wah?
The Thai land system is simple: 1 rai = 4 ngan, and 1 ngan = 100 square wah, so 1 rai = 400 square wah. Select rai as the "From" unit and the tool lists the value in ngan, square wah, square metres and more.

Does it use binary or decimal data units?
The data storage tab uses binary units, where 1 KB is 1,024 bytes, 1 MB is 1,024 KB, and so on up to TB. This matches how operating systems usually report file and drive sizes.
Can I convert temperature between Celsius, Fahrenheit and Kelvin?
