About the Number Base Converter

Number Base Converter converts numbers between bases. Programmers work with several number systems — binary (base 2), octal (base 8), decimal (base 10) and hexadecimal (base 16) — and this tool converts Number Base Converter accurately, handling multiple space-separated values at once.

How Number Base Converter works

This converts a number from one base (radix) to another. The base is how many digit symbols the system uses — binary = 2, octal = 8, decimal = 10, hexadecimal = 16, up to 36.

Worked example — 255 from base 10 to base 16:

  1. 255 ÷ 16 = 15 remainder 15 (F)
  2. 15 ÷ 16 = 0 remainder 15 (F)
  3. Read the remainders upward: FF

How to use

  1. Type or paste your value(s) into the input box.
  2. Separate multiple values with spaces to convert them all at once.
  3. The converted result appears instantly.
  4. Click Copy to copy the output.
