Decimal to Binary Converter

What is Decimal to Binary Conversion?

Decimal to Binary conversion is the process of transforming a number written in decimal (base 10) into its equivalent binary (base 2) format.

Decimal system (base 10): Uses digits 0–9. This is the number system used in everyday life.

Binary system (base 2): Uses only two digits – 0 and 1. This is the fundamental language of computers.

For example:

• Decimal 5 → Binary 101.
• Decimal 10 → Binary 1010.

 

Why Convert Decimal to Binary?

1. Education & Learning: Helps students understand how computers represent numbers.

2. Programming: Developers often need binary values for memory addresses and bitwise operations.

3. Electronics & Engineering: Circuits, microcontrollers, and processors work using binary signals.

4. Everyday Use: Useful for computer science assignments, coding tests, and system design.

 

How Decimal to Binary Conversion Works

Decimal numbers are converted to binary using repeated division by 2.

Example 1: Convert Decimal 13 to Binary.

1. 13 ÷ 2 = 6 remainder 1

2. 6 ÷ 2 = 3 remainder 0

3. 3 ÷ 2 = 1 remainder 1

4. 1 ÷ 2 = 0 remainder 1

Now read remainders from bottom to top → 1101

So, Decimal 13 = Binary 1101.
