Binary to Hexadecimal (B2X) is a conversion process that incorporates the two aforementioned number systems. The original number is in binary format, base 2, and is converted to hexadecimal format, base 16.

The conversion can be done by converting each group of 4 binary bits to their decimal counterpart, and the hexadecimal equivalent of that decimal value is the hexadecimal equivalent of those 4 bits. For example, the binary value 1010 is 10 in decimal and then 'A' in hexadecimal.

Binary is the language used by computers, but it is often too long and confusing to show, so it is often presented to the user as hexadecimal values. Hexadecimal is often used to shorten binary values because each hexadecimal value corresponds to four binary values or bits. There are 16 hexadecimal values: 0 to 9 and A to F or 0 to 15 in decimal, while there are only two values for binary: 1 and 0. Binary is often arranged in groups of 4 bits, which results in 15 if the place values of 8, 4, 2 and 1 are added.

In order to convert a binary value into hexadecimal values, the decimal equivalent of each 4-bit group must be taken over by adding the place values where 1s is displayed. In a 4-bit binary code, we add all the place values with a 1 or multiply 8421 by its aligned value. So the binary code 1010 is equal to 8 + 0 + 2 + 0, which is decimal '10' or hexadecimal 'A'.

For example, the binary value '1100 0101 1110 0110' is converted to hexadecimal:

1100 = 8 + 4 + 0 + 0 = 12 = [C] 0101 = 0 + 4 + 0 + 1 = 5 = [5] 1110 = 8 + 4 + 2 + 0 = 14 = [E] 0110 = 0 + 4 + 2 + 0 = 6 = [6] 1100 0101 1110 0110 = C5E6

Hexadecimal is much shorter than binary, so binary values, which are the actual language used by computers, are often presented to the user as hexadecimal values.
