The binary number 10110 equals 22 in decimal.
To convert binary 10110 to decimal, each digit is multiplied by 2 raised to its position power, starting from 0 on the right. Summing these gives the decimal value. For 10110, this means calculating 1×2^4 + 0×2^3 + 1×2^2 + 1×2^1 + 0×2^0, which totals 16 + 0 + 4 + 2 + 0 = 22.

Conversion Formula
The conversion from binary to decimal involves multiplying each binary digit by 2 raised to the position of the digit, counting from zero on the right. This works because binary is base-2, and each position represents 2 to the power of its place. For example, for 10110:
- 1×2^4 = 16
- 0×2^3 = 0
- 1×2^2 = 4
- 1×2^1 = 2
- 0×2^0 = 0
Adding these gives 16 + 0 + 4 + 2 + 0 = 22. This method can be used for any binary number by applying the same principle for each digit.
Conversion Example
Let’s convert 1101 to decimal:
- Step 1: Write down the number 1101.
- Step 2: Assign position values starting from right to left: 2^0, 2^1, 2^2, 2^3.
- Step 3: Multiply each digit by 2 raised to its position:
- 1×2^3 = 8
- 1×2^2 = 4
- 0×2^1 = 0
- 1×2^0 = 1
- Step 4: Sum the products: 8 + 4 + 0 + 1 = 13

Conversion Definitions
Binary
Binary is a number system that uses only two digits, 0 and 1, to represent data. It forms the foundation of digital computing, where each digit, called a bit, encodes information through its presence or absence, enabling complex calculations and data storage in electronic devices.
Decimal
Decimal is the standard base-10 number system, using digits 0 through 9. It is most familiar for everyday counting and calculations, where each position in a number represents a power of ten. Decimal numbers are widely used for general arithmetic and measurement tasks worldwide.
Conversion FAQs
What is the easiest way to verify my binary to decimal conversion?
The simplest method is to list each binary digit, multiply by 2 to the power of its position, then sum all the results. Using a calculator or spreadsheet can speed up this process, but manual calculation helps understand the underlying math better.
Why does each position in binary multiply by a power of two?
Because binary is based on powers of two, each position represents a specific power, starting from 2^0 on the right. This positional notation allows binary numbers to encode decimal values accurately, with each digit contributing according to its position’s weight.
Can I convert larger binary numbers to decimal with this method?
Yes, the same method applies regardless of size. For bigger binary numbers, just extend the process by multiplying each digit by 2 raised to its position and summing all products. Using tools like calculators or software helps handle large numbers efficiently.
