Numbers to Words Converter

Numbers to words at a glance#

A numbers to words converter turns a numeral into its written form, like 123 into "one hundred twenty-three". You read a large number by splitting the digits into groups of three from the right, then naming each group from left to right and adding its place name: thousand, million, billion, and so on.

Worked examples: 123 is "one hundred twenty-three" and 2,500 is "two thousand five hundred". Take 1,234,567,890, group it as 1 | 234 | 567 | 890, and read each group with its place name: "one billion two hundred thirty-four million five hundred sixty-seven thousand eight hundred ninety". A hundred billion (100,000,000,000) is "one hundred billion", and a trillion (1,000,000,000,000) is "one trillion".

To write an amount in words on a check, spell out the dollars, then put the cents as a fraction over 100. So $1,234.56 is "One thousand two hundred thirty-four and 56/100 dollars", and $50.75 is "Fifty and 75/100 dollars". Capitalize the first word and draw a line through any leftover space so the amount cannot be altered.

Enter any number in the converter above for the exact words, including decimals and currency. This tool uses the short-scale naming used in the US and modern UK, so a billion means a thousand million; some older or regional conventions name large numbers differently.

How to read a number out loud#

Split the digits into groups of three from the right. Read each group as a normal three-digit number, then add its place name: thousand, million, billion, and so on. The rightmost group has no place name. Hyphenate compound numbers from 21 to 99, like twenty-three or sixty-seven.

Writing large numbers#

Take 1,234,567,890 and group it as 1 | 234 | 567 | 890. Reading left to right gives one billion, two hundred thirty-four million, five hundred sixty-seven thousand, eight hundred ninety. One million is 1,000,000 and one billion is 1,000,000,000. This page uses the short scale, where a billion is a thousand million.

Decimals and currency#

For a decimal, read the whole-number part, say "point", then read the digits after the point one at a time: 0.678 is zero point six seven eight. For money on a check, spell out the dollars, then write the cents as a fraction over 100. So $1,234.56 is "One thousand two hundred thirty-four and 56/100 dollars", and $50.75 is "Fifty and 75/100 dollars".
