# Binary to Decimal Conversion

Binary to Decimal Conversion is essential to computer science and math. It converts a base-2 binary number to a base-10 decimal number. Since decimal numbers are more widespread, this translation makes binary numbers easier to understand and manipulate. By translating binary to decimal, people can bridge the gap between computer binary and human decimal.

## Definitions of binary and decimal

Binary numbers use only 0 and 1. Bits are binary digits whose values depend on their positions. Humans utilize decimal, which has ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. decimal notation bases digit values on powers of 10. Understanding binary to decimal conversion requires knowing the definitions of binary and decimal.

## Binary-to-decimal conversion importance

Binary numbers fuel our digital world, and you’ll master decoding them by the end. Binary to decimal conversion is essential for computer science students, hobbyist programmers, and computer enthusiasts. Jump in!

## Basic Binary and Decimal Numbers

The decimal number system we use daily must be understood before understanding binary numbers. Decimal numerals use 0–9 and represent powers of 10 with place values. Example: 243 in decimal implies 2 x 100 + 4 x 10 + 3 x 1.

Binary numbers work similarly but utilize only 0 and 1. Place values are powers of 2. The rightmost digit is valued at 2^0 = 1. Next position left has place value 2^1 = 2. Thus, 2^2 = 4, 2^3 = 8, etc.

Binary number 101 is 1 x 4 + 0 x 2 + 1 x 1, which is 5. 1100 is a binary number with a decimal value of 12. See the pattern?

Converting binary to decimal is useful in many technical disciplines. Add the place values of each binary digit to convert. Like ordinary math, start right and work left. Zero and one are worth their place values.

## Take 10101’s binary to decimal conversion:

1×16=16 (2^4) Zero x 8 equals 0 (2^3)
1×4=4 (2^2) x2 = 0 (2^1) x = 1 (2^0 place value). _________ Total: 21

Binary 10101 = decimal 21. Not difficult! Binary to decimal conversion can be automatic with practice. Mastering this essential ability will let you explore new technical concepts.

## Steps to Convert Binary to Decimal

Binary to decimal conversion is simple if you know the basics. The key is understanding how binary numbers represent values with two digits, 0 and 1. Once you understand that, you’ll convert quickly.

First, use positional notation. The value of each binary digit depends on its position. Reading from right to left, the first place is 2^0 (1), the second is 2^1 (2), the third is 2^2 (4), and so on. In decimal, 1010 is 18 + 04 + 12 + 01 = 8 + 2 = 10.

The second strategy is doubling. Double the value for each place from right to left. So for 1010,:

1 * 1 = 1 0 * 2 = 0 1 * 4 = 4 1 * 8 = 8 1 + 0 + 4 + 8 = 13

## Third, use the binary-to-decimal formula:

Binary Digit * 2^n = Decimal. Start at 0 for n to the right.

For 1010: In decimal form, (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (0 * 2^0) = 8 + 0 + = 10.

For binary fraction conversion, use the formula: Decimal = (Binary Digit * 2^-n) where n is the left position starting at 1.

It takes practice to perfect this conversion. To practice, convert some binary numbers to decimal. You’ll quickly master coding, network addressing, and circuit design!

## Converting Binary to Decimal Examples

Once you get used to it, binary to decimal conversion is easy. Let’s demonstrate with a few instances.

Example 1: Decimalizing a 4-bit binary number

Consider the 4-bit binary number 0101. Steps to convert to decimal:

Right-hand binary number with least significant bit: 0101

Starting from 1 for the rightmost bit, assign place values to each bit position: 8 4 2 1

Multiply binary digits by place values: 0 x 8 = 0 1 x 4 = 4 0 x 2 = 0
1 x 1 = 1

Put Step 3’s goods together: 0 + 4 + 0 + 1 = 5

The decimal equivalent of 4-bit binary 0101 is 5.

Example 2: Decimalizing an 8-bit binary number

• Try 01100101, an 8-bit number. Here are the steps:
• Write the 8-bit binary number with the least significant bit on the right: 01100101
• From 128 to 1, assign place values to bit positions: 128 64 32 16 8 4 2 1
• Multiply binary digits by place values:
0 x 128 = 0
1 x 64 = 64
1 x 32 = 32
0 x 16 = 0
0 x 8 = 0
1 x 4 = 4
0 x 2 = 0 1 x 1 = 1
• Put Step 3’s goods together: 0 + 64 + 32 + 0 + 0 + 4 + 0 + 1 = 101

The decimal equivalent of 01100101 is 101. You’ve mastered it! Binary-to-decimal conversion can be easy with practice.

## Real-World Binary to Decimal Conversion Uses

Programming and network addressing employ binary code. Knowing how to convert binary to decimal is crucial.

Many software developers use binary code, which computers can process. Humans struggle to read binary code (0s and 1s). Programmers develop code in Python or Java and compile it into binary for the computer. The ability to translate binary, decimal, and hexadecimal helps debug code.

IP addresses identify network devices in binary. Four portions of an IP address can each contain eight binary digits, such as 11000000 10101000 00000001 00000111. These are converted to decimal by network administrators to get 192.168.1.7. Subnet masks, which define network segments, must be converted from binary to decimal.

### Digital circuits and electronics

Many digital electrical circuits and components, including microprocessors, employ binary signals and codes to represent instructions and data. Programs and interfaces employ decimal notation, even while components use binary. Programming and using these devices requires number system conversion.

Many applications use binary-to-decimal conversion. Many jobs require knowledge of number systems and how to convert them as technology becomes more digital. These changes can become automatic with practice.
