The Hex to Decimal Calculator is an easy-to-use online tool designed to instantly convert hexadecimal numbers into their decimal, binary, and octal equivalents. Whether you’re a programmer, student, or electronics hobbyist, this tool helps you quickly translate between number systems without doing manual calculations.

Hexadecimal numbers (base 16) are widely used in computer programming, digital electronics, and networking. While they’re compact and efficient for machines, humans often need to interpret them in decimal form or other bases. This calculator removes the guesswork, providing you with instant, accurate results.

How to Use the Hex to Decimal Calculator

Using the calculator is straightforward and requires no technical expertise. Here’s how:

  1. Enter the Hexadecimal Value
    • Type your hex value into the input field (e.g., 1A3F or 0x1A3F).
    • The input is automatically converted to uppercase for consistency.
  2. Click the “Calculate” Button
    • Once clicked, a progress bar will appear, simulating the conversion process for clarity.
  3. View the Results
    • The calculator displays:
      • Hexadecimal (with 0x prefix)
      • Decimal equivalent
      • Binary equivalent
      • Octal equivalent
    • A detailed explanation of the conversion process is also shown.
  4. Copy or Share Results
    • Use the Copy Results button to store them on your clipboard.
    • Or use Share Results to send via supported apps or copy a shareable link.
  5. Reset for a New Calculation
    • Click Reset to clear inputs and start fresh.

Practical Example

Let’s say you have the hexadecimal value:

CopyEdit1A3F

Step-by-step conversion:

  • 1 × 16³ = 4096
  • A (10) × 16² = 2560
  • 3 × 16¹ = 48
  • F (15) × 16⁰ = 15

Total Decimal Value:

yamlCopyEdit4096 + 2560 + 48 + 15 = 6719

Binary:
0b1101000111111

Octal:
0o15077

With the calculator, you simply enter 1A3F, press Calculate, and all these results are displayed instantly—no manual math required.
