Number Conversion Calculator

In the digital world, numbers aren’t just written in decimal (base 10). Computers work in binary (base 2), color codes often use hexadecimal (base 16), and programmers sometimes work with octal (base 8) or even base 36 for compact data representation.

The Number Conversion Calculator is a powerful online tool designed to instantly convert numbers between multiple numeral systems — including binary, octal, decimal, hexadecimal, and base 36. Whether you’re a student learning about number systems, a programmer working with data formats, or an engineer dealing with digital logic, this tool saves time and ensures accuracy.

How to Use the Number Conversion Calculator

Using the calculator is straightforward. Here’s a step-by-step guide:

1. Enter the Number
   • Type your number into the Input Number field.
   • Make sure it’s valid for the base you’re converting from (e.g., binary numbers should contain only 0s and 1s).
2. Select the “From Base”
   • Choose the base of your current number:
     • 2 – Binary
     • 8 – Octal
     • 10 – Decimal
     • 16 – Hexadecimal
     • 36 – Base 36
3. Select the “To Base”
   • Choose the base you want to convert the number into.
4. Click “Calculate”
   • The tool will display a short progress animation for a smooth experience.
5. View the Results
   • The converted number appears along with:
     • Your original input
     • The “From Base” and “To Base” selections
     • The decimal equivalent for reference
6. Optional – Copy or Share Results
   • Click Copy Results to copy the details to your clipboard.
   • Click Share Results to send the conversion to others instantly.

Practical Example

Example: Convert a binary number 101101 to hexadecimal.

• Step 1: Enter 101101 into the input field.
• Step 2: Set “From Base” to Binary (2).
• Step 3: Set “To Base” to Hexadecimal (16).
• Step 4: Click “Calculate.”
• Step 5: Result shows:
  • Converted Number: 2D
  • Decimal Equivalent: 45

This quick process lets you verify and use conversions in programming, networking, or educational projects.
