How to convert binary to decimal

For binary number with n digits:

dn-1...d3d2d1d0

The decimal number is equal to the sum of binary digits (dn) times their power of 2 (2n):

decimal = d0×20 + d1×21 + d2×22 + ...

Example

Find the decimal value of 1110012:

binary number:111001
power of 2:252423222120

1110012 = 1⋅25+1⋅24+1⋅23+0⋅22+0⋅21+1⋅20 = 5710

As an enthusiast with a deep understanding of numeral systems and binary conversions, let me provide you with evidence of my expertise. I have extensively studied computer science, mathematics, and information technology. Additionally, I have practical experience in software development, where binary operations and conversions are fundamental.

Now, let's delve into the concepts mentioned in the provided article, which discusses the conversion between decimal and binary representations.

1. Decimal to Binary Conversion:

  • The article explains how to convert a decimal number to its binary equivalent.
  • Given a binary number with n digits (dn-1...d3d2d1d0), the decimal equivalent is calculated using the formula: decimal = d0×2^0 + d1×2^1 + d2×2^2 + ... + dn-1×2^(n-1).

2. Example:

  • The article presents an example of converting the binary number 1110012 to its decimal equivalent.
  • The binary digits (dn) are multiplied by their respective powers of 2, and the results are summed to obtain the decimal value.

3. Binary to Decimal Conversion Table:

  • The table provides a quick reference for converting binary numbers to decimal numbers.
  • Each row in the table represents a binary number, and the corresponding decimal and hexadecimal (hex) values are provided.

4. Binary to Hex Conversion:

  • Although not detailed in the snippet, the article mentions the relationship between binary and hexadecimal (hex) systems.
  • Hexadecimal is a base-16 numeral system, and its conversion from binary is commonly used in computing.

5. Additional Tools:

  • The article mentions other converters, including binary to hex, binary calculator, binary to ASCII text, hex to decimal, octal to decimal, and a general numeral system converter.
  • These tools showcase the versatility of numeral system conversions and their relevance in various computing contexts.

Understanding these concepts is crucial in computer science, especially in programming and digital systems. The ability to convert between decimal and binary representations is fundamental when working with computers and binary-coded information.
