Frequently Asked Questions
What is hexadecimal?
Hexadecimal is base-16 numbering using digits 0-9 and letters A-F (representing 10-15). It's commonly used in computing for memory addresses and color codes.
How do I convert hex to decimal?
Multiply each digit by 16 raised to its position power (starting from 0 on the right), then sum. Example: 2A = 2×16¹ + 10×16⁰ = 42.
Why use hex in programming?
Hex is more compact than binary and aligns perfectly with bytes (2 hex digits = 1 byte). It's easier to read than long binary strings.
