The SWAP button will help you to switch between Binary to Decimal and Decimal to Binary.

Conversion steps:

1. Pick the last integer of the binary number, and call this digit the current digit.
2. Consider a variable ‘power’. Set the value to 0.
3. Multiply the current digit with a 2^power value, and store the result.
4. Increment the power by 1.
5. Set the current digit to the previous digit of the binary number.
6. Follow step 3 until all digits have been multiplied.
7. Add all the results of step 3 to get the decimal number answer.

For Example:

(111100000001)B = (1 × 2¹¹) + (1 × 2¹⁰) + (1 × 2⁹) + (1 × 2⁸) + (0 × 2⁷)
+ (0 × 2⁶) + (0× 2⁵) + (0 × 2⁴) + (0 × 2³) + (0 × 2²) + (0 × 2¹) + (1 × 2⁰)

(111100000001)B = (3841) D

## Binary System

Binary is the simplest type of number system that makes use of only two numbers 1 and 0. By using these numbers, arithmetical problems can be solved by machines because, in digital instruments, a transistor is used in two states. Those two states can be represented by 0 (False) and 1 (True). That’s why this number system is the most chosen in modern computer engineering, networking, and communication technologies by specialists, and other professionals.

## Decimal System

The decimal number system is also known as the Base 10 numbering system because it is based on 10 ranging symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. In the decimal system, every digit holds its own position along with the decimal point. I.e. the number 326.34 has 4 in the Hundredths position, 3 in the Tenths position, 6 in the Unit position, 2 in the Tens position, and 3 in the Hundreds position.

A Decimal number system is also one of the ancient numeral systems, whose roots are in the Hindu-Arabic numeral system.
