Number to Words Conversion Rules

1. Basic Numbers (0-19)

These numbers have unique names: zero, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen.

2. Tens (20-90)

Multiples of ten have specific names: twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety. Numbers in between combine the tens name with a hyphen and the ones digit (e.g., twenty-one, thirty-five).

3. Hundreds

Numbers from 100-999 use the pattern: [digit] hundred [and] [remaining]. For example: 123 = one hundred twenty-three, 500 = five hundred.

4. Thousands and Beyond

Large numbers are grouped in sets of three digits, each group named by its scale: thousand, million, billion, trillion. Each group follows the same hundreds pattern. For example: 1,234,567 = one million two hundred thirty-four thousand five hundred sixty-seven.

5. Negative Numbers

Negative numbers simply add the word 'negative' or 'minus' before the number. For example: -42 = negative forty-two or minus forty-two.

6. Zero

The number 0 is written as 'zero'. In some contexts, it may also be called 'oh' or 'naught', but this converter uses 'zero' as the standard form.
