How Does the Words to Number Converter Work?
Paste or type a number written in English words and the converter parses it into its numeric value. Small words like "twenty-three" add to the running total, while scale words like hundred, thousand, million, and billion multiply what has been read so far. Hyphens, commas, and "and" are accepted, and "point" supports decimals such as "one point five".
Example
"one hundred twenty three" converts to 123. "one million two hundred thousand" converts to 1,200,000. "two hundred fifty five" converts to 255. If a word is not recognized, the converter stops and explains the problem instead of guessing.
Common Use Cases
- Converting an amount written on a check into digits before entering it.
- Turning spelled-out figures from contracts or documents into spreadsheet numbers.
- Verifying that a number written in words matches the numeric amount.
- Helping students check their spelling of large numbers in words.
FAQs
What number formats are supported?
English cardinal words from zero up to trillions, with hyphens ("twenty-three"), commas ("one hundred, five"), and "and" ("one hundred and five") all accepted. Decimals are supported with "point" followed by digit words.
How does the parser handle "one million and fifty"?
"million" multiplies the one (1,000,000), then fifty adds 50, giving 1,000,050. Scale words carry their multiplier to whatever number word precedes them.
What happens if the input is invalid?
The converter shows a clear error message instead of an empty result, such as when a word is not recognized, a scale word is missing its number, or "hundred" is preceded by a value greater than nine.
