Conversion Formula
The formula for converting binary to decimal involves multiplying each binary digit by 2 to the power of its position, counting from right to left starting at zero. Summing all these results gives the decimal number.
Mathematically, for binary number bₙbₙ-1...b₁b₀, the decimal value is:
decimal = b₀ * 2⁰ + b₁ * 2¹ + ... + bₙ * 2ⁿ
For example with 11010:
- Rightmost digit (0): 0 * 2⁰ = 0
- Next digit (1): 1 * 2¹ = 2
- Next digit (0): 0 * 2² = 0
- Next digit (1): 1 * 2³ = 8
- Leftmost digit (1): 1 * 2⁴ = 16
Adding these up: 0 + 2 + 0 + 8 + 16 = 26
Conversion Example
Let's convert 1011 binary number to decimal step-by-step:
- Digits from right to left: 1, 1, 0, 1
- Calculations:
- 1 * 2⁰ = 1
- 1 * 2¹ = 2
- 0 * 2² = 0
- 1 * 2³ = 8
Sum: 1 + 2 + 0 + 8 = 11 in decimal.

Conversion Definitions
Binary
Binary is a number system with base 2, using only two digits: 0 and 1. It’s used in digital electronics and computing because it easily maps to the on-off states of electronic switches and transistors.
Decimal
Decimal is a base-10 number system, consisting of ten digits from 0 to 9. It’s the standard counting system used worldwide, where each digit's position represents a power of 10 in the number's value.
Conversion FAQs
How does binary 11010 convert to decimal?
The conversion involves multiplying each digit by 2 raised to its position power, then summing all the products. For 11010, the calculation results in 26, as shown in the step-by-step example.
Is there a quick way to convert binary 11010 without calculations?
Yes, using a calculator or binary-to-decimal conversion tool can quickly give the decimal equivalent. Recognizing patterns or memorizing small binary values also helps for quick conversions.
What happens if I input a binary number with digits other than 0 or 1?
The conversion tool will identify invalid digits since binary only uses 0 and 1. Inputting other digits like 2 or 3 will result in an error message or invalid input indication.
Can I convert binary 11010 to decimal manually?
Absolutely, by multiplying each digit by 2 to the power of its position and adding the results, the manual process confirms the value as 26 in decimal.
Why is binary useful in computer systems?
Binary simplifies electronic design because transistors can be either off (0) or on (1), making data processing and storage more reliable and efficient compared to other number systems.
