Step 2: Write 8, 4, 2 and 1 below each group. If the leftmost group doesn’t have enough digits to make up a set of four, add extra 0’s to make a group. Step 1: Write down the binary number and group the digits (0’s and 1’s) in sets of four.

The method is easier than it sounds but it’s always useful to use a binary to hex conversion chart to save time. It follows that four binary digits will be equal to one hex digit. You just need to remember that each hex digit represents four binary digits. How to Convert Binary to HexĬonverting from binary to hex is easy since hexadecimal numbers are simplified versions of binary strings. In html programming, colors can be represented by a 6-digit hexadecimal number: FFFFFF represents white whereas 000000 represents black. In hex, these can be represented in a friendlier fashion, ranging from 00 to FF. This means one byte can carry binary values from 0000 0000 to 1111 1111. Each hex digit represents four binary digits therefore, hex is a language to write binary in an abbreviated form.įour binary digits (also called nibbles) make up half a byte.

Hex is used in mathematics and information technologies as a more friendly way to represent binary numbers. The letters are used because of the need to represent the values 10, 11, 12, 13, 14 and 15 each in one single symbol. These are the 10 decimal digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and the first six letters of the English alphabet (A, B, C, D, E, F).

As a base-16 numeral system, it uses 16 symbols. I am just adding here how to convert from Decimal and Hex to binary using pure Bash.The hexadecimal system (shortly hex), uses the number 16 as its base (radix).

As mentioned in previous answer you can do Binary to Decimal and Hexa Decimal as follows in Bash using echo and printf.
