How are rupees and paise separated?

The amount is multiplied by 100 and rounded to whole paise, then divided back into rupees and paise. This integer approach avoids floating-point drift, so 125000.50 yields exactly 125000 rupees (ரூபாய்) and 50 paise (பைசா).

What number scale does it use?

It uses the Indian system: ஆயிரம் (thousand), லட்சம் (lakh = 100,000), and கோடி (crore = 10,000,000). So a large amount groups by lakhs and crores, not by Western millions, matching how figures are written across South India.

Why do some Tamil number words change form?

Tamil numbers undergo sandhi when joined, so the prefix form differs from the standalone form. Twenty-one is இருபத்தி ஒன்று and a hundred with a remainder uses நூற்றி. The tool stores these combining forms so the output reads naturally.

What does மட்டும் at the end mean?

மட்டும் means 'only' and is the customary closing on Tamil cheques and financial documents. It signals the written amount is complete, guarding against later additions, so the tool appends it automatically.

Is the amount sent anywhere?

No. The conversion uses built-in Tamil numeral tables and runs entirely in your browser. The amount you enter is never uploaded, logged, or stored.

Rupee amounts, written out in Tamil

Cheques, invoices, and legal papers in Tamil Nadu and across South India require the amount in words as well as figures. Getting it right means using the Indian lakh and crore scale, naming rupees and paise correctly, and applying Tamil’s sandhi rules so the words join naturally. This tool produces that phrasing from a plain rupee amount.

How it works

The amount is first converted to whole paise to avoid floating-point error: it is multiplied by 100, rounded, then split into rupees and paise.

total_paise = round(amount × 100)
rupees      = floor(total_paise / 100)
paise       = total_paise mod 100

Each part is spelled out with the Tamil number engine, which uses the Indian scale — ஆயிரம் (thousand), லட்சம் (lakh), கோடி (crore) — and the correct combining forms (இருபத்தி for twenty, நூற்றி for a hundred with a remainder). The rupees take ரூபாய், the paise take பைசா, and the phrase closes with மட்டும்.

Tips and notes

Because the paise split is integer-based, you never get a stray hundredth from binary floating point — 125000.50 is exactly fifty paise. Note that Tamil written numerals shift form when combined: 21 is இருபத்தி ஒன்று, not இருபது ஒன்று. The closing மட்டும் mirrors the English “only” on a cheque.
