Dear forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

Maybe this information about the Thai length and area units may be of use for you.

It correctly says that the Wah (or Talang Wah) is exactly 2m. The Rai is 400 square Wah or 1600 square meters.

The site currently states 1.91m for a Wah (with an indication that this value is an approximation).
