Frequently Asked Questions
Hexadecimal (hex) is a base-16 number system using digits 0-9 and letters A-F. Each hex digit represents 4 binary bits, making it a concise way to write binary values.
Divide the decimal number by 16 repeatedly, recording the remainder (0-15, where 10=A, 11=B, etc.). Read the remainders from bottom to top.
Hex is compact (one hex digit = 4 binary bits) and maps neatly to bytes (2 hex digits = 1 byte). It's used for color codes, memory addresses, and viewing binary data.
