What is a Binary Number?

A binary number is a number expressed using only two digits: 0 and 1. This numbering system is known as the base-2 numeral system and is the core language of computers. Every digit in a binary number represents an increasing power of 2 from right to left.

What is Decimal Format?

The decimal system is the standard number system used in everyday life. It is a base-10 system, meaning it includes ten digits from 0 to 9. Computers often convert between binary and decimal formats during processing and output representation.

How to Convert Binary to Decimal Manually

Binary to decimal conversion can be done by multiplying each digit in the binary number by 2, raising the power of its position (from right to left), and then summing all those values.

Manual Conversion Steps:

  1. Write down the binary number.
  2. Start from the rightmost digit (least significant bit).
  3. Multiply each digit by 2 raised to its position index.
  4. Add all resulting values to get the decimal number.

Binary to Decimal Conversion Example

Input: 01100011
Output: 99

Step-by-step Calculation:

Bit Position Binary Digit 2^Position Value
7 0 2^7 = 128 0
6 1 2^6 = 64 64
5 1 2^5 = 32 32
4 0 2^4 = 16 0
3 0 2^3 = 8 0
2 0 2^2 = 4 0
1 1 2^1 = 2 2
0 1 2^0 = 1 1

 

Total: 64 + 32 + 2 + 1 = 99
