How to Use Number Base Converter (Step-by-Step)

1

Enter Number

Type your number in any input box (Binary, Dec, Hex, or Octal).

2

All other bases calculate and update live as you type.

3

Copy Converted Value

Copy the converted number with one click.

Technical Architecture & Execution Mechanics

Positional Radix Number Systems

A number in base B is evaluated as the sum of digits multiplied by powers of B: Value = Sum(Digit_i * B^i). Conversions parse to BigInt and format via toString(radix).

Decimal_Value = parseInt(Number_String, Source_Radix)

Technical Limitations & Operational Constraints

  • Fractional floating-point base conversions (e.g. binary fractions) are rounded to integer representation.

Key Specifications & Capabilities

  • 4 Major Radix Bases – Binary (2), Octal (8), Decimal (10), Hexadecimal (16)
  • Custom Radix Support – Convert to any base between 2 and 36
  • BigInt Precision – Converts arbitrarily large integers without overflow
  • Instant Local Math – Computes directly in browser memory

Frequently Asked Questions & Answers

How do I convert Hexadecimal to Binary?

Each hex digit converts directly to 4 binary bits (e.g. Hex 'F' = Binary '1111', Hex 'A' = Binary '1010').

Are my files uploaded, analyzed, or stored on NexVaani servers?

Where supported, tool inputs and files are processed locally inside your web browser using WebAssembly and HTML5 Canvas. Your files are not uploaded to NexVaani file-processing servers.
