Questions fréquentes

How do I enter hexadecimal digits A-F?

This calculator uses numeric input only. For hex digits A-F, convert them to their decimal equivalents: A=10, B=11, C=12, D=13, E=14, F=15. For example, hex 'FF' is entered as 255.

What is the maximum value I can enter?

The maximum input is 4294967295, which corresponds to hex FFFFFFFF (8 hex digits).

Why is the result the same as the input?

Because the input is already a decimal number representing the hex value. The calculator simply displays that number as the decimal equivalent.

Hexadecimal to Decimal Conversion

d = Σ (h_i × 16^i)

Each hex digit is multiplied by 16 raised to its position power, then summed.

Example:

Input: hex = 2F (entered as 47)

Calculation: 2×16^1 + 15×16^0 = 32 + 15

Result: 47

Conseils et erreurs courantes

Tips

  • Remember that hex digits A-F correspond to 10-15.
  • For large hex numbers, break them into groups of four digits for easier conversion.
  • Use the calculator to verify your manual conversions.

Common Mistakes to Avoid

  • Confusing hex digits with decimal numbers (e.g., treating 'A' as 1 instead of 10).
  • Forgetting to multiply each digit by the correct power of 16.
  • Entering letters directly into the numeric input field.

Hypothèses et limites

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
