Number to Words Converter
Spell out any number in English or Spanish words — plain words, cheque/check writing with the currency, money amounts in words, or ordinals (first, twenty-third) — with decimals, UK “and”, Indian lakh and crore, and letter-case options.
How it works
English: split the whole part into groups of three digits, name each group (hundreds, then tens and ones) and add its scale word — thousand, million, billion, trillion · Indian English: last three digits, then pairs — thousand, lakh (10⁵), crore (10⁷) · Spanish: groups of six — mil inside each group, then millón (10⁶) and billón (10¹²) · Cheque: whole amount in words + cents as ⁿⁿ/100 · Ordinal: change the last word (one → first, twenty → twentieth)
English number words are built in groups of three digits: within each group you name the hundreds, then the tens and ones, and after the group you attach its scale word. American usage writes 1,234 as “one thousand two hundred thirty-four”; British usage adds “and” before the last part: “one thousand two hundred and thirty-four”. The Indian system groups the last three digits and then pairs, so 12,34,567 is “twelve lakh thirty-four thousand five hundred sixty-seven”, and the calculator uses it automatically for rupee amounts. Spanish works in groups of six with the long scale — mil millones is a US billion and un billón is a US trillion — and changes “uno” to “un” or “una” to agree with the noun: veintiún pesos, veintiuna libras, un millón de pesos. For cheques the whole amount is spelled out and the cents are written as a fraction of 100, for example “One thousand two hundred thirty-four and 56/100 dollars”; Mexican peso cheques end in “56/100 M.N.” and Indian cheques read “Rupees … only”. Decimals can be read digit by digit (point five six), as a number (point fifty-six) or as a fraction (fifty-six hundredths), and ordinals turn the last word into first, second, twentieth and so on.
Worked example
1234.56 splits into the groups 1 | 234, giving “one thousand two hundred thirty-four”, and the decimals are read “point five six”. On a US cheque the amount line is “One thousand two hundred thirty-four and 56/100 dollars”, and in words it is “one thousand two hundred thirty-four dollars and fifty-six cents”. In Spanish it is “mil doscientos treinta y cuatro pesos con cincuenta y seis centavos”, or “Mil doscientos treinta y cuatro pesos 56/100 M.N.” on a Mexican cheque. ₹1,25,000 is “Rupees one lakh twenty-five thousand only”, and 23 as an ordinal is “twenty-third” (vigésimo tercero).
