Quick Examples:

This tool converts numbers between bases. You can convert decimal, binary, hexadecimal, and octal numbers. It works with whole numbers and numbers with fractions.

How to Use This Tool

  1. Enter a number:

    Type the number you want to convert. You can include a fraction. Use normal number formats. For hexadecimal, binary, and octal numbers, include the prefix if needed (such as 0x, 0b, or 0o).

  2. Select the Original Base:

    Choose the base that your input number uses. For standard decimals, choose “Decimal (Base 10)”.

  3. Select the Target Base:

    Pick the base you want to convert to. For example, choose “Binary (Base 2)” if you want a decimal to binary conversion.

  4. Set Decimal Precision:

    This field controls how many decimal places appear in the result when you convert a fraction. The default value is 8.

  5. Convert the Number:

    Click “Convert” to perform the conversion. The tool shows the result and may provide a step-by-step conversion process for detail.

  6. Clear the Inputs:

    If you wish to start over, click “Clear” to reset the fields.

Understanding the Output

The result displays your original number in its base along with its conversion. You see both the number and the base labels. This helps you compare both formats side by side.

If you are converting from or to decimal, a step-by-step process is shown. This process breaks down how each part of the number is calculated.

Limitations and Special Notes

  • The tool accepts valid number formats only.
  • Errors are shown if the input does not match the chosen base.
  • It supports both whole numbers and decimal fractions.
  • The tool automatically picks the right base if you add a prefix.

Common Use Cases

  • If you want to convert a decimal number like 42 into binary.
  • If you need to convert a binary number to decimal for programming tasks.
  • If you are exploring number systems in an academic setting.
  • If you work with different number formats in computing.

A Bit of Background

Decimal numbers use 10 digits: 0 to 9. This is the system we use every day. Binary numbers use only 0 and 1. Computers prefer binary because it is simple.

For example, the binary number 101 means 1 × 2² + 0 × 2¹ + 1 × 2⁰, which equals 5 in decimal.

Step-by-Step Example: Converting 13 from Decimal to Binary

  1. Divide 13 by 2. You get 6 as the quotient and 1 as the remainder.
  2. Divide 6 by 2. The quotient is 3 and the remainder is 0.
  3. Divide 3 by 2. The quotient is 1 and the remainder is 1.
  4. Divide 1 by 2. The quotient is 0 and the remainder is 1.

Read the remainders from bottom to top. The binary equivalent is 1101.

Step-by-Step Example: Converting a Decimal Fraction

Consider the fraction 0.625. Multiply 0.625 by 2. The result is 1 with a remainder fraction of 0.25.

Multiply 0.25 by 2. The result is 0 with a fraction of 0.5.

Multiply 0.5 by 2. The result is 1.

The conversion gives 0.101 in binary. Read the digits in order to get the final answer.
