Decimal to Binary Converter


A Decimal to Binary Converter is a free online tool that allows you to convert numbers from decimal (base-10) representation to binary (base-2) representation. In everyday life and most mathematical contexts, we commonly use the decimal numbering system, which includes digits from 0 to 9. In contrast, binary is a base-2 system, which uses only two digits: 0 and 1.

The process of converting decimal numbers to binary numbers involves repeatedly dividing the decimal number by 2 and recording the remainders until the quotient becomes zero. The binary representation is constructed by reading the remainders from bottom to top. Here are the steps for converting a decimal number to binary:

  • Start with the decimal number you want to convert.
  • Divide the decimal number by 2.
  • Record the remainder (either 0 or 1).
  • Continue dividing the quotient by 2 and recording the remainders until the quotient becomes zero.
  • Read the recorded remainders from bottom to top to obtain the binary equivalent.

For example, to convert the decimal number 13 to binary:

  • 13/2 = 6 remainder 1
  • 6/2 = 3 remainder 0
  • 3/2 = 1 remainder 1
  • 1/2 = 0 remainder 1

Reading the remainders from bottom to top (1, 1, 0, 1), we get the binary representation 1101.

A Decimal to Binary Converter automates this process, making it much quicker and error-free, especially for larger decimal numbers. It's a useful tool for programmers, engineers, and anyone working with binary data who needs to convert decimal values into binary format for various calculations and applications.
