Thai Numerals

Foundations

Thai digits ๐–๙ represent the same values as 0–9. Read the digits in the complete number: ๑๐๐ is 100 and ๙๙ is 99. The surrounding words tell you whether a number is a price, an address, or a count.

How It Works

1. Match The Digits
The Thai digits are ๐ ๑ ๒ ๓ ๔ ๕ ๖ ๗ ๘ ๙. Their values, in that order, are 0 1 2 3 4 5 6 7 8 9. Check each digit in a complete number rather than guessing from its shape.

2. Keep The Place Value
๑๐๐ represents 100: one hundred, zero tens, and zero units. ๙๙ represents 99. In บ้านเลขที่ ๙๙/๑, keep the slash as part of the address notation; the example identifies house number 99/1, not a calculation.

3. Read The Number In Thai
The choice of digit shapes does not create a different set of number words. ๑๑ is read สิบเอ็ด and ๒๐ is read ยี่สิบ. Compare the complete naming patterns in numbers 11 to 99.

4. Read The Surrounding Words
ราคา ๑๐๐ บาท shows a price of 100 baht. แมว ๒ ตัว counts two cats, with the classifier ตัว after the number. These examples show different uses of numbers; the digit shapes alone do not determine the sentence structure or level of formality.

5. Check The Message Context
๕ is the digit five, whose Thai name is ห้า. The displayed laughter example writes repeated fives as ๕๕๕, using the sound of ห้า for wordplay. In an ordinary number context, those same Thai digits represent 555. Read the surrounding message before choosing the interpretation.

Examples (4)

  1. ราคา ๑๐๐ บาท

    Price: 100 Baht

    Word by Word: price 100 Baht

    ราคา introduces the price, ๑๐๐ represents 100, and บาท names the currency. The example states a price of 100 baht.

  2. บ้านเลขที่ ๙๙/๑

    House number 99/1

    Word by Word: house number 99 / 1

    บ้านเลขที่ introduces a house number. Read ๙๙/๑ as the address notation 99/1 and retain the slash.

  3. ๕๕๕

    Hahaha (in a laughter message)

    Word by Word: 555

    This illustration uses repeated Thai fives for “ha ha ha,” based on the number name ห้า. As an ordinary number, the same digits represent 555.

  4. แมว ๒ ตัว

    Two cats

    Word by Word: cat 2 [classifier]

    แมว names cats, ๒ represents two, and ตัว is the classifier in this counting phrase.

Common Mistakes

  • Writing ๑๑ when the task asks for twenty-two.

    ๑๑
    ๒๒

    This task asks you to write twenty-two using Thai digits. ๑๑ represents eleven. Use ๒ for each two: ๒๒ represents twenty-two.

  • Writing the number before the noun in this two-cats task.

    ๒ แมว
    แมว ๒ ตัว

    For the requested phrase “two cats,” use แมว ๒ ตัว: noun, number, then classifier. The alternative ๒ แมว does not reproduce this pattern. See Counting A Noun for its complete counting examples.
