How to Convert Hex to Octal?

Converting hexadecimal (Base 16) to octal (Base 8) is typically done by first converting the hex number to binary or decimal, and then converting that result to octal. Our tool automates this using high-precision BigInt algorithms, allowing you to convert even massive hex strings instantly.

Conversion Example

To convert Hex 1F to Octal:

  1. Convert 1F (Hex) to Decimal: (1 × 16¹) + (15 × 16⁰) = 16 + 15 = 31 (Decimal)
  2. Convert 31 (Decimal) to Octal: 31 ÷ 8 = 3 remainder 7. So, 31₁₀ = 37₈.
  3. Result: 1F₁₆ = 37₈.

Hexadecimal & Octal Basics

  • Hexadecimal (Base 16): Uses base 16 numbering, common in programming.
  • Octal (Base 8): Uses base 8 numbering (0-7).

Frequently Asked Questions

How to convert hex to octal?

The easiest way is to convert hex to binary first, then group the bits into sets of three to get the octal digits. For example, 1A hex is 0001 1010 binary, which groups as 011 010 to become 32 octal.

Is there a limit to the hex number size?

No, our tool uses JavaScript's BigInt technology, allowing you to convert hexadecimal strings of virtually any length with 100% mathematical precision.

Can I convert hex with '0x' prefix?

Yes, our converter automatically detects and handles common hex prefixes like 0x or #, as well as spaces or newlines in your input data.

Is my data secure?

Absolutely. All processing happens locally in your browser. Your hexadecimal and octal data never leaves your computer or gets sent to any server.
