Frequently Asked Questions

How do you read a hexadecimal number?▾

Each hex digit is a power of sixteen using 0-9 and A-F (A=10 … F=15). FF₁₆ is 15×16 + 15 = 255 in decimal.

Why is hexadecimal common in computing?▾

One hex digit maps to exactly four binary bits, so long binary values such as colors and memory addresses stay compact. #FF0000 is a familiar example.
