Octal to HEX Converter

Octal to Hexadecimal Converter

An octal to hexadecimal (hex) converter is a tool or program that allows you to convert a number from the octal numeral system (base-8) to the hexadecimal numeral system (base-16). Here's a simple explanation of how the conversion can be done:

1. Begin with the octal number that you want to convert.

2. Group the octal digits into sets of three digits, starting from the rightmost digit. If there are any remaining digits on the left, consider them as a separate group.

3. Now, convert each group of three octal digits into its equivalent hexadecimal representation. You can use a conversion table or follow the following mapping:

   - Octal: 0 1 2 3 4 5 6 7

   - Hex: 0 1 2 3 4 5 6 7 8 9 A B C D E F

4. Write down the hexadecimal equivalents for each group of three digits, from left to right.

5. Finally, combine all the hexadecimal digits obtained from each group to get the hexadecimal representation of the original octal number.

For example, let's convert the octal number 75 to hexadecimal:

1. Grouping the digits: 7 | 5

2. Converting each group: 7 (octal) = 111 (binary) = 7 (hexadecimal) | 5 (octal) = 101 (binary) = 5 (hexadecimal)

3. Combining the results: 75 (octal) = 75 (hexadecimal)

Therefore, the octal number 75 is equivalent to the hexadecimal number 75.

You can use an online octal to hexadecimal converter or implement a program to automate this conversion process for more complex conversions.
