About this interactive

What you're seeing: a tool that converts binary numbers into hexadecimal. Why it matters: hex is the shorthand IT professionals actually use day to day — MAC addresses, IPv6 addresses, memory dumps, and color codes are all written in hex because it's far more compact than writing out long strings of binary. How to use it: you'll be given a binary value and asked to convert it to hex yourself, with immediate feedback on whether your answer is correct.

Hexadecimal
Hex
A base-16 number system using digits 0–9 and letters A–F; each hex digit maps to exactly 4 bits, making it a compact shorthand for representing binary data.
Nibble
A group of exactly 4 bits, equivalent to one hexadecimal digit; two nibbles make up one byte.
Bit
Short for binary digit, the smallest unit of data in computing, holding a single value of 0 or 1; all digital information is ultimately composed of bits.
