Frequently Asked Questions
How do you convert hex to decimal?
Multiply each hex digit by 16 raised to its position (counting from 0 on the right), then add the results. For example, 1F = (1 × 16¹) + (F × 16⁰) = 16 + 15 = 31.
What does 0x mean in front of a hex value?
0x is a common prefix used in programming to mark a value as hexadecimal (base 16) rather than decimal. This converter accepts input with or without the 0x prefix.
Can this handle very large hex values?
Yes. The converter uses arbitrary-precision arithmetic, so values far larger than a standard 64-bit integer still convert correctly.
