Frequently Asked Questions
Hexadecimal is a base-16 number system that uses sixteen distinct symbols: the numbers 0-9 and letters A-F. It's commonly used in computing as a more human-friendly way to represent binary data.
Hexadecimal is widely used in computing because it provides a more concise way to represent binary data. One hex digit represents 4 binary digits (bits), making it easier to read and write binary values.
In hexadecimal, each digit can be 0-9 or A-F (where A=10, B=11, ..., F=15). For example, 2A in hex = 2×16¹ + 10×16⁰ = 32 + 10 = 42 in decimal.
