How to Convert Binary Numbers to Decimal
What is Binary Number System?
Binary number system is a positional numeral system with base 2, using only two digits: 0 and 1. All computers and digital devices operate with binary numbers, making understanding binary to decimal conversion critically important.
Algorithm for Converting Binary to Decimal
To convert a binary number to decimal, use the positional value formula:
- Each position has a power of 2 value (right to left: 2⁰, 2¹, 2², 2³...)
- Multiply each digit by the corresponding power of two
- Add all the resulting products
Example: Converting Number 1010
Binary number: 1010
- 1 × 2³ = 1 × 8 = 8
- 0 × 2² = 0 × 4 = 0
- 1 × 2¹ = 1 × 2 = 2
- 0 × 2⁰ = 0 × 1 = 0
Decimal number: 8 + 0 + 2 + 0 = 10
Applications of Binary Code
- Programming — bitwise operations and masks
- Computer Architecture — processors and memory
- Network Technologies — IP addressing and protocols
- Digital Signal Processing — data encoding
- Embedded Systems — microcontrollers and IoT
