Octal to Hexadecimal Converter

What is Octal to Hexadecimal Conversion?

Conversion from octal to hex means changing a number from the octal (base-8) system to the hexadecimal (base-16) system. This conversion is sometimes required in science, digital electronics, and various branches of mathematics. Octal and hexadecimal are widely used in coding and programming, and if you need to convert octal to hex, having a fast and accurate octal to hexadecimal converter can help you save time and make your work easier.

For example, if you have an octal number and want to find its equivalent value in hexadecimal, our octal to hexadecimal converter does it in no time. Just use the tool, and it provides the result without requiring manual calculations.

What is the Octal Number System?

The octal number system is a base-8 numeral system that uses digits from 0 to 7. It’s often used in digital systems because each octal digit represents three binary digits (bits), simplifying binary code interpretation. In this system:

• Each position in an octal number represents a power of 8.
• The rightmost digit represents 8⁰, the next digit represents 8¹, and so on.

For example, in the octal number 157:

• 7 represents 8⁰ or 1.
• 5 represents 8¹ or 8.
• 1 represents 8² or 64.

Thus, the decimal equivalent of 157 in octal is (1×64) + (5×8) + (7×1) = 87.

What is the Hexadecimal Number System?

The hexadecimal number (base-16) system uses sixteen symbols, including digits 0 to 9 and letters a to f (representing 10 to 15). Hexadecimal numbers are often used in computing to represent binary data compactly and with fewer digits.

For example, in the hexadecimal number 1A3:

• 3 represents 16⁰ or 1.
• A (or 10) represents 16¹ or 16.
• 1 represents 16² or 256.

So, the decimal equivalent of 1A3 in hexadecimal is (1×256) + (10×16) + (3×1) = 419.

How to Convert Octal to Hexadecimal

Converting an octal number to hexadecimal involves changing the number to binary first and then from binary to hexadecimal:

1. Convert Octal to Binary: Each octal digit is represented by three binary digits. For example, the octal number 157 converts to binary as:
   • 1 in octal becomes 001 in binary.
   • 5 in octal becomes 101 in binary.
   • 7 in octal becomes 111 in binary.
   • Thus, 157 in octal is 001101111 in binary.
2. Binary to Hex: Divide the binary digits into groups of four (starting from the right) and convert each group into a hexadecimal digit. In our example, binary 001101111 becomes 0011 (3 in hexadecimal) and 0111 (7 in hexadecimal), resulting in the hexadecimal number 37.
