Binary to Hex

Enter a binary number and convert it to hexadecimal, decimal, and octal. Results appear instantly in your browser.

Binary to Hex Converter

This tool converts binary (base 2) numbers into their hexadecimal (base 16), decimal (base 10), and octal (base 8) equivalents. Since each hex digit maps to exactly four binary digits, this conversion is especially common when working with memory addresses, machine code, or network protocols.

The conversion runs entirely in your browser using JavaScript's BigNumber library for precision.

How to use

  1. Type or paste a binary number into the input field (e.g. 11111111 or 10101100).
  2. Click Convert to see the hexadecimal, decimal, and octal results.
  3. Use the Copy button to copy the hex result to your clipboard.
  4. Click Clear to reset all fields.

Binary to hex relationship

Each hexadecimal digit represents exactly four binary digits (bits). This makes the conversion straightforward: group the binary digits into sets of four from right to left, then convert each group to its hex equivalent. For example, 10101100 becomes AC in hexadecimal.

Example

Binary:      10101100
Hexadecimal: AC
Decimal:     172
Octal:       254

MCP integration

MCP (Model Context Protocol) lets AI agents and apps discover and run Coding.Tools utilities for repeatable conversions, formatting, hashing, and generation workflows.

MCP tool name: binary-to-hex

MCP endpoint: https://coding.tools/mcp

Call tools/list first. Each tool entry includes inputSchema, outputSchema, and examples so an AI agent or client can build valid arguments without guessing.

For tools/call, read result.content[0].text for the display value and result.structuredContent for machine parsing. Tool-level failures return isError: true; protocol failures return a JSON-RPC error.

Example tools/call request:

curl -s https://coding.tools/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "MCP-Protocol-Version: 2025-06-18" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"binary-to-hex","arguments":{"input":"111100001010"}}}'

Most text and data tools accept an input string plus optional options. Browser-only image tools are listed for discovery and return a web UI link when they need browser image APIs.
