Octal to Decimal Converter

What is Octal to Decimal Conversion?

Octal to Decimal conversion is the process of converting a number from the octal system (base-8) into the decimal system (base-10).

Octal (base-8): Uses digits 0–7.

Decimal (base-10): Uses digits 0–9 (our standard number system).

 

Why Convert Octal to Decimal?

1. Programming & Coding: Octal numbers appear in low-level programming.

2. Digital Electronics: Octal simplifies binary representation.

3. Linux/UNIX Systems: File permissions use octal notation.

4. Education: Essential for learning number systems.

 

How Octal to Decimal Conversion Works

Each digit in an octal number represents a power of 8, similar to how decimal uses powers of 10.

Formula:

Decimal = (d_n \times 8^n) + (d_{n-1} \times 8^{n-1}) + … + (d_0 \times 8^0)

Example Conversion:

• Convert 234 (Octal) to Decimal:
• (2 × 8²) + (3 × 8¹) + (4 × 8⁰)
• (2 × 64) + (3 × 8) + (4 × 1)
• 128 + 24 + 4 = 156 (Decimal)
• So, 234 (Octal) = 156 (Decimal).
