Short scale vs long scale

This converter uses the short scale, where a billion is one thousand million (1,000,000,000). The short scale is standard in American English, Canadian English, and modern British English. The long scale — where a billion is one million million — is used in some European languages. Most English-language legal and financial documents expect the short scale.

Frequently asked questions

What is a number to words converter used for?

Writing out amounts on cheques, contracts, and invoices; generating accessible text for screen readers; and formatting numbers in legal documents where numerals alone are ambiguous.

Does it handle negative numbers?

Yes. Negative values are prefixed with the word negative.

What is the short scale?

In the short scale, each new term (million, billion, trillion) is one thousand times the previous. It is standard in English-speaking countries.

Is there a size limit on the number?

The converter handles numbers up to the range representable in standard JavaScript integers. For most practical purposes — cheques, contracts — this is more than sufficient.
