Understanding Binary Numbers

What is Binary?

Binary is a base-2 number system that uses only two digits: 0 and 1. It's the fundamental language of computers and digital systems.

In binary:

  • Each position represents a power of 2
  • The rightmost digit is 2⁰ (1)
  • Moving left, each position is the next power of 2: 2¹ (2), 2² (4), 2³ (8), etc.
  • A digit of 1 means that power of 2 is included in the sum
  • A digit of 0 means that power of 2 is not included

Binary to Decimal Conversion

To convert binary to decimal:

  1. Identify the position of each 1 in the binary number (from right to left, starting at 0)
  2. Calculate 2 raised to the power of each position
  3. Sum all these values

Example: 1010₂

  • 1 × 2³ = 1 × 8 = 8
  • 0 × 2² = 0 × 4 = 0
  • 1 × 2¹ = 1 × 2 = 2
  • 0 × 2⁰ = 0 × 1 = 0
  • Sum: 8 + 0 + 2 + 0 = 10₁₀

Common Binary to Decimal Conversions

1010₂
= 10₁₀
1100₂
= 12₁₀
1111₂
= 15₁₀
10000₂
= 16₁₀
10101₂
= 21₁₀
11111₂
= 31₁₀

Binary in Computing

Why Computers Use Binary

  • Electronic circuits have two states: on (1) and off (0)
  • Binary is reliable and less prone to errors
  • It's easier to implement in hardware
  • All data in computers is ultimately stored as binary

Common Binary Units

Unit Size Description
Bit 1 bit A single binary digit (0 or 1)
Nibble 4 bits Half a byte
Byte 8 bits Can represent 256 values (0-255)
Word 16/32/64 bits Depends on processor architecture

How Does Binary to Decimal Conversion Work?

The Binary to Decimal Converter uses the positional notation method, where each binary digit (bit) is multiplied by powers of 2 based on its position. Here’s the fundamental process our Binary to Decimal Converter follows:

Binary to Decimal Formula

Decimal=∑i=0n−1di×2i

Where:

  • d_i = binary digit at position i

  • n = total number of binary digits

  • i = position from right (starting at 0)

Step-by-Step Binary to Decimal Conversion Process

Method 1: Positional Notation (Used by Our Binary to Decimal Converter)

StepDescriptionExample with 1101₂
1Identify positions from right to left1(2³) 1(2²) 0(2¹) 1(2⁰)
2Calculate powers of 28 + 4 + 0 + 1
3Sum the results13₁₀
 

Method 2: Doubling Method

  1. Start from leftmost digit

  2. Double previous result and add current digit

  3. Continue until all digits processed
