Converting numbers to words is essential for many professional and personal applications. This free online tool helps you spell out numbers accurately and instantly.
Large numbers are written by grouping digits into sets of three from right to left. For example, 1,234,567 is "one million two hundred thirty-four thousand five hundred sixty-seven". Use commas to separate groups when writing digits, and use words like "thousand", "million", "billion" for scale.
Common rules: Spell out numbers one through nine, use digits for 10 and above. Always spell out numbers at the start of a sentence. In technical or scientific writing, use digits more liberally. For formal documents like checks or contracts, always write out the full amount in words.
Decimals are written using "point" followed by each digit spelled individually. For example, 3.14 is "three point one four". For currency, use "and" for cents: $25.50 is "twenty-five dollars and fifty cents".
Cardinal numbers (one, two, three) indicate quantity or count. Ordinal numbers (first, second, third) indicate position or order. Use ordinal numbers for dates (January 1st), rankings (3rd place), and sequences (the fifth chapter).
Negative numbers are written with "negative" or "minus" before the number. For example, -42 is "negative forty-two" or "minus forty-two". In financial contexts, negative numbers might be called "in the red" or written in parentheses.
