Conversion Formula
The conversion from binary to decimal involves summing each binary digit multiplied by 2 raised to its position power. The rightmost digit is position 0, and each move to the left increases the position by 1. This works because binary is a base-2 system, where each position represents a power of 2.
For example, in binary 10110: the rightmost 0 is 0×2^0, the next 1 is 1×2^1, the next 1 is 1×2^2, the next 0 is 0×2^3, and the leftmost 1 is 1×2^4. Summing these: 0 + 2 + 4 + 0 + 16 = 22.
Conversion Example
- Number: 1101
- Step 1: List digits from right to left: 1, 0, 1, 1
- Step 2: Assign position values: 2^0, 2^1, 2^2, 2^3
- Step 3: Multiply each digit by 2 raised to its position: 1×2^3 + 1×2^2 + 0×2^1 + 1×2^0
- Step 4: Calculate: 8 + 4 + 0 + 1 = 13

Conversion Definitions
Binary
Binary is a number system that uses only two digits, 0 and 1, to represent all numbers. It is used by digital systems and computers because it aligns with the on-off states of electronic circuits, making data processing simple and reliable.
Decimal
Decimal is a base-10 number system that uses ten digits from 0 to 9. It is the most common system for everyday counting and calculations, with each position representing a power of 10. It’s the standard numbering system used globally for general purposes.
Conversion FAQs
How do I convert a binary number like 10110 to decimal manually?
To convert 10110, write down each digit with its position from right to left starting at 0. Multiply each digit by 2 to the power of its position. Sum all the results. For 10110, it’s 1×2^4 + 0×2^3 + 1×2^2 + 1×2^1 + 0×2^0, which totals 22.
What happens if I enter a non-binary number in the conversion tool?
If the input contains digits other than 0 or 1, the script detects invalid characters and will show "Invalid binary" message. Binary numbers only allow 0s and 1s, so any other digit makes the number invalid for conversion.
Can I convert binary to decimal using programming languages?
Yes, most programming languages have built-in functions or methods to convert binary strings into decimal numbers. For example, in JavaScript, parseInt('10110', 2) will give 22, simplifying the conversion process in code.
Is the conversion from binary to decimal always reversible?
Yes, converting back from decimal to binary is also possible by dividing the decimal number repeatedly by 2 and recording the remainders. This makes binary and decimal conversions bidirectional, ensuring data integrity.
