How to Convert Binary to Decimal: The Easiest Step-by-Step Guide

=>Introduction:-

Have you ever wondered how computers understand numbers? While we use the Decimal system (0–9), computers use Binary (0 and 1). In this post, I will show you exactly how to convert any binary number to a decimal number in just three simple steps.

Step 1: Write down the Binary Number

Let’s use the example: 1011.

Step 2: Assign Powers of 2

Starting from the right side, assign each digit a power of 2, beginning with 2^0.

1. 1*2^3 = 8

2. 0*2^2 = 0

3. 1*2^1 = 2

4. 1*2^0 = 1

Step 3: Add them up...

Now, simply add the results: 8 + 0 + 2 + 1 = 11.

So, the binary number 1011 is 11 in decimal!
