    Questions
    What are the Thai numerals?

    Thai has its own ten digits: ๐ ๑ ๒ ๓ ๔ ๕ ๖ ๗ ๘ ๙. They work exactly like 0–9, so ๒๕๖๙ is 2569.

    Are Thai numerals still used?

    Yes, next to 0–9. You'll see them on banknotes and coins, in government documents and on traditional signs, while most everyday writing uses 0–9.

    How do Thai number words work?

    Say each digit followed by its place: สิบ (10), ร้อย (100), พัน (1,000), หมื่น (10,000), แสน (100,000) and ล้าน (1,000,000). So 1,234 is หนึ่งพันสองร้อยสามสิบสี่.

    Why is 11 สิบเอ็ด and 20 ยี่สิบ?

    A 1 at the end of a longer number becomes เอ็ด, a 2 in the tens place becomes ยี่, and a 1 in the tens place is just สิบ.

    How do you say a billion in Thai?

    Thai counts in millions. A billion is หนึ่งพันล้าน (a thousand million) and a trillion is หนึ่งล้านล้าน (a million million).

    What is baht text?

    The amount in words, as written on cheques and receipts. Whole amounts end in บาทถ้วน and satang are added after, so 100.50 is หนึ่งร้อยบาทห้าสิบสตางค์.

    How do I convert a year to the Thai calendar?

    Add 543. The year 2026 is พ.ศ. ๒๕๖๙. Subtract 543 to go back.
