Binary to Hex — Practice

About this interactive

What you're seeing: a guided walkthrough that turns a binary value into hex one bit at a time, in groups of four. Why it matters: every binary-to-hex conversion is the same move — split the bits into groups of four and each group maps to exactly one hex digit. How to use it: step through the bits in Guided mode collecting each nibble's place values (8, 4, 2, 1) until its fourth bit resolves the sum to a hex digit, then switch to Solo to convert the full value yourself.

Key terms

Binary
The base-2 number system that uses only the digits 0 and 1; the native language of digital computers, which store and process data as electrical on/off states.
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.
Place Value
The weight assigned to a digit based on its position within a number; in binary, each position represents a successive power of 2 (1, 2, 4, 8, …), making position the key to decoding binary values.
