You might be intimidated about converting hex to binary, but the method is actually quite straightforward. Hexadecimal, or simply hex, is a base 16 system. Try the Binary to Hex Converter too! How to Convert Hexadecimal to Binary
Read (or watch) our tutorial on How to Convert Hexadecimal to Binary to learn more about the process of converting hex to binary. Optionally, you can Copy the output to clipboard, or Save it as a file on your device. The Binary Number output will appear in the second field.īelow that, you can also review the results of the conversion in base numbers. Press the Convert button below the first number field. You need 48 bits to store a MAC address.Enter an Hexadecimal Number in the first field. A bit is a space in computer memory which can be either set to 0 or 1. What this means is that for a number that we could write with 12 hexadecimal digits, we’d need 48 binary digits to write the same. We have to write 12 hexadecimal digits, how many possibilities do we have? 16¹², essentially. And for hexadecimal, you’d have 16 * 16 possibilities. For binary, you’d have 2 * 2 = 4 possibilities. What if you had to write 2 digits? For decimal, you’d have 10 * 10 possibilities (This essentially means that you can write any number from 00 to 99). If you had to write a hexadecimal digit, you’d have 16 possibilities. If you had to write a decimal digit, you’d have 10 possibilities. If you could write one binary digit, how many possibilities would you have? Well, 2. Now imagine that you can write 1 digit on a piece of paper. That’s why you’ll never see any other symbols being used in a mac address, apart from colons or dashes which are used as separators. Usually we use the first six symbols of the English alphabet, namely - a, b, c, d, e, and f. We already have 10 digits - 0 to 9, we need six more symbols. Its written in the number system which uses 16 digits, called the hexadecimal number system. The mac address that appears to be a string of length 12 is actually a number. In fact, the same is true for number systems using any number of digits, be it 2 (binary), 10 (decimal, the regular representation we use), or some other integer greater than 2.
using 10 symbols - 0, 1, 2, …, 8, 9 can be represented in binary as well. All of the numbers that can be represented in the “regular” way, i.e. You already may know about binary, a number system where we only use two symbols - 0, and 1. This is because the MAC address representation you see is called hexadecimal. You might have noticed that your MAC address does not have any other alphabets than a, b, c, d, e and f. Why is the MAC address called 48 bit when it is 12 characters in length?
