How to Convert Binary to Decimal Manually

While our tool helps to automatically and quickly convert binary to decimal, you can also do it manually by using the following steps.

1. Starting with the farthest right digit of your binary number, multiply each of the digits by the powers of 2.
2. Begin with 20 and then increase the exponent by one when you reach the next digit as you move from right to left down the number. So the next is 21, then 22 and so on.
3. After multiplying each digit, add the sum of each digit together, and your result is the decimal number.
