How to Convert Binary to Decimal: A Step-by-Step Guide
How to Convert Binary to Decimal?
Have you ever wondered how to convert binary numbers to decimal? In this guide, we will explain the step-by-step process of converting binary numbers to decimal numbers. By understanding this concept and learning the calculations involved, you will be able to convert binary to decimal effortlessly. Let's dive in!
The Basics of Binary and Decimal Systems
Before we delve into the conversion process, let's briefly understand what binary and decimal systems are. The binary system is a base-2 numbering system that uses only two digits: 0 and 1. On the other hand, the decimal system (also known as the base-10 system) is the numbering system we commonly use, which consists of ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
Binary System:
The binary system follows a positional notation, where each digit's value depends on its position. The rightmost digit represents the units place, the next digit to the left represents the twos place, the next digit represents the fours place, and so on. Each digit's value is obtained by multiplying the corresponding position value by 2 raised to the power of the position.
Converting Binary to Decimal
Converting binary numbers to decimal involves understanding the positional values of each digit in the binary number and performing simple mathematical calculations. Here's a step-by-step guide to converting binary numbers to decimal:
| Binary Digit Position | 8 | 4 | 2 | 1 |
|---|---|---|---|---|
| Binary Digit Value | 1 | 0 | 1 | 1 |
1. Start by writing down the binary number you want to convert.
2. Assign the positional values 8, 4, 2, and 1 to the bits from left to right.
3. Multiply each digit by its corresponding positional value.
4. Sum up the results of all the calculations to obtain the decimal equivalent of the binary number.
Example Conversion: Binary 1011 to Decimal
Let's illustrate the conversion process with an example. We will convert the binary number 1011 to its decimal equivalent.
| Binary Digit Position | 8 | 4 | 2 | 1 |
|---|---|---|---|---|
| Binary Digit Value | 1 | 0 | 1 | 1 |
1. Binary number: 1011
2. Positional values: 8, 4, 2, 1
3. Calculation: (1 x 8) + (0 x 4) + (1 x 2) + (1 x 1)
4. Decimal equivalent: 11
