    FAQ

    Can hexadecimal digits be lowercase?

    Yes. This converter accepts both uppercase and lowercase hex letters — '3e8' and '3E8' are treated as the same value, and both convert to decimal 1,000.

    How do you convert hexadecimal to decimal?

    Multiply each hex digit by 16 raised to its position (counting from 0 on the right) and add the results. For example, hex 3E8 = (3×16²) + (14×16¹) + (8×16⁰) = 768 + 224 + 8 = 1,000.

    What is the largest hexadecimal number this converter accepts?

    Up to 15 hex characters, close to the maximum integer size on a 64-bit system — for example, 'fffffffffffffff' converts to the decimal number 1,152,921,504,606,846,975.
