Hexadecimal is a number system that consists of 16 digits, from 0-9 and A-F. This base 16 system is normally used to display binary values in a much cleaner and shorter format. This is because for every 4 bits, you can represent 1 hex number, making it super convenient! Hexadecimal is also used to shorten decimal values, and is employed everywhere from programming to cybersecurity and cryptography. For that reason, knowing how to easily convert hexadecimal numbers to decimal is a good skill to have!
