What Is FREE TOOLS Binary Converter Calculator?
A Binary Converter Calculator is a free online tool that converts numbers between the binary number system (base 2) and other common number systems, such as decimal (base 10), hexadecimal (base 16), and octal (base 8).
Binary numbers use only two digits:
0 and 1
They are fundamental to computers, programming, digital electronics, and data processing.
How Does a Binary Converter Calculator Work?
The calculator converts a number from one number system to another while keeping its mathematical value the same.
For example, to convert binary 1011 to decimal:
1011₂ = (1 × 2³) + (0 × 2²) + (1 × 2¹) + (1 × 2⁰)
= 8 + 0 + 2 + 1
= 11₁₀
Therefore:
1011₂ = 11₁₀
