Number to Words (Turkish) Converter

How it is calculated

The number is split into groups of three digits from the right, and the groups are named with the Turkish scale words: bin (thousand), milyon, milyar, trilyon and katrilyon. Each group is spelled as hundreds, tens and ones (yüz, on, yirmi … and bir, iki, üç …), then its scale word follows. A leading one is dropped before yüz and before bin: 100 is yüz and 1000 is bin, but 1,000,000 is bir milyon.

Words are written separately with spaces, as Turkish does: 21 is yirmi bir. A negative number gets the prefix eksi, and 0 gives sıfır (never “eksi sıfır”). The input must be a whole number up to 9,007,199,254,740,992 (2⁵³) in absolute value; a fraction such as 12.75 or a larger number gives no result instead of a cut-off word.

Common mistakes

• Entering an amount with decimals, such as 12.75, and expecting the kuruş part to be written. A fraction is refused and no result appears, so enter the whole part (12 gives on iki) and write the kuruş separately.
• Typing a decimal comma (3,5). The field expects a whole number, and a value with a comma gives no result.
• Entering a number above about 9 quadrillion (2⁵³). Beyond that point a computer number can no longer hold every digit exactly, so the tool shows no result.
• Expecting “bir yüz” or “bir bin”. In Turkish these are written just yüz and bin, which is what the tool outputs, while a lone one before a million stays (bir milyon).
• Copying the text onto a cheque or invoice without checking the formal style of that document. Some forms ask for the amount in capitals or with the currency name added, which the tool does not do.
