Frequently Asked Questions
Why is hexadecimal used in computing?
Hex is compact — one hex digit represents exactly 4 bits. This makes it easy to read binary data. For example, 0xFF is much easier to read than 11111111.
How do I convert hex to decimal manually?
Multiply each hex digit by 16 raised to its position (right to left, starting from 0). For example: 1A = 1×16¹ + 10×16⁰ = 16 + 10 = 26.
