Hexadecimal was adopted in the first place because it's so easy to convert between the two. Essentially, hexadecimal is used as a way to display binary information in a shorter string. This chart is all you need to convert from one to the other: [1] X Research source Hexadecimal Binary 0 1 2 3 4 5 6 7 8 9 A B C D E F Try it yourself.
It really is as simple as changing the digit into the four equivalent binary digits. Here are a few hex numbers for you to convert. Understand why this works. In the "base two" binary system, n binary digits can be used to represent 2 n different numbers. This makes conversion between the two systems extremely easy. Hexadecimal counts " D, E, F, 10 " at the same time binary counts ", , , ". Part 2. Review how base ten works.
You use decimal notation every day without having to stop and think about the meaning, but when you first learned it, your parent or teacher might have explained it to you in more detail. A quick review of how ordinary numbers are written will help you convert the number: [3] X Research source Each digit in a decimal number is in a certain "place.

To put it mathematically, the "places" represent 10 0 , 10 1 , 10 2 , and so on. This is why this system is called "base ten," or "decimal" after the Latin word for "tenth. Write a decimal number as an addition problem. Here the rules are the same as above except we avoid the rightmost zeros in this case. These are called trailing zeros. That is 0. This can be achieved by combining the above tables. Let us try to summarize the rules:. Write the hexadecimal number neatly.
Underneath each digit write the corresponding decimal digit. Underneath each decimal term write the corresponding binary digit. String together all the digits, without any space in between. Rewrite the answer after leaving out leading and trailing zeros. We have obtained our final answer. Decimal Digit Binary Digit 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 E 9 A A 3 8 To convert:. Example - convert decimal 22 to hexadecimal. Result - Example - convert to hexadecimal.
Result - 8A. Example - to hex. Result - D. Break into groups of four - Result - C3. In this example, extra 0s are added at the highest values to create two groups of four bits.
