What Is FREE TOOLS Octal to Hexadecimal Converter?
A FREE TOOLS Octal to Hexadecimal Converter is an online calculator that converts numbers from the octal number system (base 8) into the hexadecimal number system (base 16).
Octal uses the digits 0–7, while hexadecimal uses 0–9 and A–F.
How Does an Octal to Hexadecimal Converter Work?
The easiest conversion method is:
Octal → Binary → Hexadecimal
Each octal digit represents 3 binary bits, while each hexadecimal digit represents 4 binary bits.
Example: Convert 157₈ to Hexadecimal
Step 1: Convert octal to binary
- 1₈ = 001₂
- 5₈ = 101₂
- 7₈ = 111₂
So:
157₈ = 001 101 111₂
Remove unnecessary leading zeros:
001101111₂
Step 2: Group binary digits into groups of 4
0000 0110 1111
Convert each group to hexadecimal:
- 0000 = 0
- 0110 = 6
- 1111 = F
Therefore:
157₈ = 6F₁₆
