Conversion Formula
The conversion from binary to decimal is done by multiplying each binary digit by 2 to the power of its position from right to left, then summing these values. Formula: decimal = Σ(digit × 2^position).
This works because binary is base-2, so each position represents a power of 2. For example, binary 1011 equals 1×2^3 + 0×2^2 + 1×2^1 + 1×2^0 = 8 + 0 + 2 + 1 = 11.
Conversion Example
- Binary: 1101
- Step 1: Assign positions starting from 0 on the right: 1(3), 1(2), 0(1), 1(0)
- Step 2: Calculate each: 1×2^3=8, 1×2^2=4, 0×2^1=0, 1×2^0=1
- Step 3: Sum all: 8+4+0+1=13
- Therefore, binary 1101 equals decimal 13.
- Binary: 1010
- Step 1: Positions 1(3), 0(2), 1(1), 0(0)
- Step 2: 1×8=8, 0×4=0, 1×2=2, 0×1=0
- Step 3: Sum: 8+0+2+0=10
- So, binary 1010 is decimal 10.
- Binary: 111
- Step 1: Positions 1(2), 1(1), 1(0)
- Step 2: 1×4=4, 1×2=2, 1×1=1
- Step 3: Sum: 4+2+1=7
- Thus, binary 111 converts to decimal 7.

Conversion Definitions
Binary
Binary is a base-2 numbering system that uses only two digits, 0 and 1, to represent numbers. It is fundamental in digital electronics and computing because it aligns with the on/off states of digital circuits, enabling efficient data processing and storage.
Decimal
Decimal is a base-10 numbering system that employs ten digits, 0 through 9, to represent numbers. It is the most common system used in everyday life, relying on powers of ten for place value, making it easy to understand and perform calculations.
Conversion FAQs
How do I convert binary 1001011 to decimal step by step?
First, write down the binary digits with their positions from right to left: 1(6), 0(5), 0(4), 1(3), 0(2), 1(1), 1(0). Then, multiply each digit by 2 raised to its position: 1×2^6=64, 0×2^5=0, 0×2^4=0, 1×2^3=8, 0×2^2=0, 1×2^1=2, 1×2^0=1. Add these: 64+0+0+8+0+2+1=75.
Is there a quick way to convert binary 1001011 to decimal without calculation?
Yes, you can use online converters or calculator functions that recognize binary input and convert it directly to decimal, saving time and reducing errors. Also, knowing the value of certain binary patterns helps estimate the decimal value quickly.
Why does binary 1001011 equal 75 and not a different number?
This is because each position in the binary number represents a power of 2, and when the digits are multiplied by these powers and summed, the total results in 75. The pattern of 1s and 0s determines the specific sum, which in this case is 75.
Can I convert larger binary numbers to decimal the same way?
Yes, the process is the same for any size of binary number. You assign positions starting from 0 on the right, multiply each digit by 2 raised to its position, and add all the products. As numbers grow, calculations may become more complex but follow the same rules.
Are there any common pitfalls in binary to decimal conversion?
Common mistakes include miscounting positions, forgetting to multiply by the correct power of 2, or misreading the binary digits. Double-checking the positions and ensuring each digit is correctly processed helps avoid errors.
