Binary to Decimal
A Binary to Decimal Converter is a handy tool that allows users to convert binary numbers (base-2) into their equivalent decimal (base-10) representation. Binary numbers consist of only two digits: 0 and 1, while decimal numbers use digits from 0 to 9. This conversion is essential in computer science, digital electronics, and programming.

How Does a Binary to Decimal Converter Work?
The tool follows a simple mathematical process to convert binary numbers to decimal:
-
Understand Binary Position Values:
Each digit in a binary number represents a power of 2, starting from the right (least significant bit).
Example:1011
(binary) can be broken down as:-
1 × 2³ = 8
-
0 × 2² = 0
-
1 × 2¹ = 2
-
1 × 2⁰ = 1
-
-
Sum the Values:
Add all the calculated values:8 + 0 + 2 + 1 = 11
(decimal) -
Result:
The binary number1011
is equal to11
in decimal.
