Converting Decimal to Hexadecimal

There are several ways to convert decimal (sometimes called denary, or base 10) numbers into hexadecimal (base 16).

The video below gives a step by step guide on how to convert decimal numbers into binary code using the ‘divide by 16’ method.

Here’s how it works:

1. Divide the decimal number by 16.
2. If the number will not divide equally by 16, then round down the answer to the nearest whole number (integer).
3. Keep a note of the remainder, it should be between 0 and 15.
4. Keep repeating the above steps, dividing each answer by 16, until you reach zero.
5. Write out all the remainders, from bottom to top.
6. Finally, convert any remainders bigger than 9 into hexadecimal letters. This is your solution.
