How to convert binary number to decimal number?

Step 1: Start from right most bit.

Step 2: Multiply the right most bit with 2 and 2 is assigned with poswer 0. e.g; 2⁰

Step 3: Now move to left bits one by one. Value of power is incremented on after each one bit.

Example 1:

Convert the 110101 into its equivalent decimal number system.

Solution:

110101₂  = (1*2⁵)+(1*2⁴)+(0*2³)+(1*2²)+(0*2¹)+(1*2⁰)

=	32  +  16   +  0   +  4  +  0   +  1

= 53

Example 2:

Convert the 110101 into its equivalent decimal number system.

Solution:

110011₂  = (1*2⁵)+(1*2⁴)+(0*2³)+(0*2²)+(1*2¹)+(1*2⁰)

=	32  +  16   +  0   +  0  +  2   +  1

= 51
