Why is hexadecimal used instead of binary?

Hexadecimal writes bytes in a much shorter form, using two digits per byte instead of eight bits. It is commonly used for color codes like #FF8800 and memory addresses.

How do I convert binary to hex by hand?

Split the binary number into groups of four bits starting from the right, adding leading zeros if needed. Then match each 4-bit group to its hex value from 0 to 9 or A to F.
