Satang are rounded to 2 places. The Thai wording follows the usual rules for documents: 21 is ยี่สิบเอ็ด, 101 is หนึ่งร้อยเอ็ด, and whole amounts end in ถ้วน.
Questions
When is “ถ้วน” used?
When there are no satang: 500 baht is “ห้าร้อยบาทถ้วน”. It marks the end of the amount so nothing can be added after it.
How is 1 read at the end of a number in Thai?
As “เอ็ด” when other digits come before it (21 ยี่สิบเอ็ด, 101 หนึ่งร้อยเอ็ด), and as “หนึ่ง” on its own (1, or 0.01 as หนึ่งสตางค์).
How should the amount be written in English on a cheque or invoice?
Usually with each word capitalised and “Only” at the end when there are no satang, as in “One Thousand Two Hundred Fifty Baht Only”.
What about more than 2 decimal places?
They're rounded to satang, half up: 1.005 becomes 1.01 baht.
