From Base-8 to Base-16: The Computing Connection 🔢

Both the octal (base-8) and hexadecimal (base-16) number systems are used in computing as compact, human-readable representations of binary data. Being able to translate between them is a useful skill, especially when working with different systems or legacy code.

The Conversion Bridge: Binary

The easiest and most reliable way to convert from octal to hexadecimal is to use binary (base-2) as an intermediate step. The process is a simple two-step translation:

Let's convert the octal number `247` to hexadecimal:

  1. Convert Octal to Binary: Convert each octal digit to its 3-bit binary equivalent.
    • 2 → 010
    • 4 → 100
    • 7 → 111
    • Combined Binary: 010100111
  2. Re-group Binary for HEX: Take the binary string and re-group it into chunks of 4 bits, starting from the right. Pad the leftmost group with zeros if needed.
    • 0 1010 0111 → 0000 1010 0111
  3. Convert Binary to HEX: Convert each 4-bit group to its hexadecimal digit.
    • 1010 → A
    • 0111 → 7
    • Final HEX (ignoring leading zeros): A7

This tool automates this entire process, giving you an accurate conversion in an instant.
