About this hex to decimal converter
Conversion from hex to decimal reads each digit as a power of 16: the hexadecimal digits 0–9 keep their value and A–F stand for 10–15, so f in hex is 15 in decimal and 0x1A is 1×16 + 10 = 26. To convert hex to decimal by hand, multiply every digit by 16 raised to its position (rightmost = 16⁰) and add the results — or paste the value above and let the translator do it.
This converter uses exact big-integer arithmetic, so values beyond 2⁵³ — where ordinary floating-point calculators silently round — convert without losing a single digit. Everything runs in your browser; nothing is uploaded.
