What Is FREE TOOLS Hexadecimal to Octal Converter?
A Hexadecimal to Octal Converter is a free online tool that converts numbers from the hexadecimal number system (base 16) into the octal number system (base 8).
Hexadecimal uses 0–9 and A–F, while octal uses only 0–7. This conversion is useful in computer science, programming, digital electronics, and number-system calculations.
How Does a Hexadecimal to Octal Converter Work?
A hexadecimal number can be converted to octal by first converting it to binary and then grouping the binary digits into groups of three.
Example: Convert 2F₁₆ to Octal
First convert hexadecimal to binary:
- 2 = 0010
- F = 1111
So:
2F₁₆ = 00101111₂
Group the binary digits into groups of three from the right:
000 101 111
Convert each group to octal:
- 000 = 0
- 101 = 5
- 111 = 7
Therefore:
2F₁₆ = 57₈
