Hex Calculator

How it works

Convert between Hexadecimal, Decimal, and Binary values instantly.

Convert between Hex, Decimal, and Binary bases

Description

The Hex Calculator is a multi-base conversion tool designed for programmers, engineers, and computer science students. It allows you to input a value in Hexadecimal (used for colors and memory addresses), Decimal (standard math), or Binary (machine code), and instantly see the equivalent values in the other two bases.

Inputs

• Hexadecimal: Supports digits 0-9 and letters A-F (e.g., 1A, FF).
• Decimal: Standard base-10 integers (e.g., 255).
• Binary: Supports digits 0 and 1 (e.g., 11010). Note: Editing any field will automatically update the others.

Outputs

• Result Cards: Displays the synchronized values for Hex, Decimal, and Binary.

Chart

• N/A: This tool provides direct base-conversion results.

“Good to Know”

• Hex in Web Design: Hexadecimal is most commonly seen in CSS as “hex codes” for colors (e.g., #FFFFFF for white).
• Nibbles and Bytes: One hex digit (0-F) represents exactly 4 bits (a nibble). Two hex digits represent 8 bits, which is a full Byte.
• Base-16 Advantage: Hex is used in computing because it is a much more compact way to read binary code. FF is easier for a human to read than 11111111.

Examples
