What Is Binary and Decimal Number System?
Binary System (Base-2)
The binary number system uses only two digits: 0 and 1. Each digit is called a bit. Computers rely on this system because it’s easy to represent binary with two states: on/off, true/false, or high/low voltage.
Decimal System (Base-10)
This is the standard number system used by humans, based on ten digits (0–9). It is a positional system, where each digit’s value depends on its position from the right.
Why Do You Need a Converter?
Converting binary numbers into decimal format helps us read and understand data coming from machines, databases, or coding environments.

How Does Binary to Decimal Conversion Work?
Step-by-Step Example
Let’s convert 1010
:
- 1 × 2^3 = 8
- 0 × 2^2 = 0
- 1 × 2^1 = 2
- 0 × 2^0 = 0
- Total = 8 + 0 + 2 + 0 = 10
Alternate Method: Double Dabble
A more programming-friendly method involves:
- Start from 0
- For each bit, double the current total and add the bit
- This results in the correct decimal value with fewer steps
