Number to Spoken Base Words
Convert digits in bases 2 through 36 to spoken place-value words for teaching, accessibility, and radix notation.
Spell digits in any radix as spoken words
When teaching binary or hexadecimal, instructors often read each symbol aloud rather than the
decimal value of the whole number. For example, binary 1011 is spoken “one-zero-one-one,”
not “eleven.” This converter spells valid digits in bases 2 through 36 using English word names,
with optional grouping (such as nibbles in base 2).
How to use this tool
- Enter the number using digits and letters allowed in your target base.
- Select the radix (2 through 36).
- Choose digit grouping for longer strings, or leave grouping off for a single hyphenated chain.
- Copy the spoken line for lesson plans, screen-reader scripts, or accessibility notes.
To convert numeric values between bases, use the Integer Base Converter or Fractional Base Converter.
Frequently Asked Questions
Does this compute the decimal value?
No. It only names each digit symbol in order; value conversion is a separate step.
How are letters A through Z pronounced?
Symbols 10 through 35 use distinct spoken names (ay, bee, cee, and so on) so homophones are avoided in audio.
What happens if a digit is invalid for the base?
The tool returns an error instead of guessing, so base-2 input cannot include the digit 2.
