## What is Binary to Decimal Conversion?

A binary number is a digital number that has base 2 and is used in computer applications. It is represented by only two digits that are 1 and 0.

A decimal number is a number with base 10 and uses all the digits from 1 to 9. It is the most commonly used number system.

To convert a binary number into a decimal, we need to multiply each digit of binary number with decreasing order of exponents of 2 and add them all together.

Suppose 1001 is a binary number. Then,

1×23+0x22+0x22+1×20

8+0+0+1

=9

Therefore, 10012 = 910
