Hex to Binary — Practice

About this interactive

What you're seeing: a guided walkthrough that turns a hex value into binary one bit at a time — four bits per hex digit. Why it matters: hex is a compact shorthand for binary precisely because every digit maps to a fixed 4-bit nibble; this interactive makes that one-to-one mapping concrete instead of abstract. How to use it: step through the bits in Guided mode, asking at each one whether the place value (8, 4, 2, 1) fits in what is left of that digit's value, then switch to Solo to read the hex value and enter the full binary string yourself.

Key terms

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.
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.
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.
