Frequently asked questions
How do I convert hex to decimal?
Read each hex digit as its value (A=10 … F=15) and multiply by powers of 16, right to left. For example FF = 15×16 + 15 = 255. Or paste it into the converter and read the decimal instantly.
What is FF in decimal?
FF (hexadecimal) is 255 in decimal — the largest value in a single byte (8 bits).
Does hex to decimal work for very large values?
