Accurate Base-8 to Base-10 Conversion
Why use this Octal to Decimal Converter? In computing environments, particularly within Unix and Linux file systems, Octal (Base-8) is frequently used to represent file permissions. However, humans think in Decimal (Base-10). This tool bridges the gap, allowing developers, students, and network administrators to verify values instantly without manual calculation errors.
Our converter eliminates the need to manually multiply digits by powers of 8. Whether you are deciphering legacy code, working on low-level programming, or completing a computer science assignment, you get the precise integer equivalent immediately. The tool enforces strict input validation, ensuring only valid octal digits (0-7) are processed.
How to Use This Tool
- Input Data: Enter a valid octal string (digits 0-7 only) into the text area.
- Execute: Click "Convert to Decimal" to process the number.
- Results: The equivalent Base-10 integer appears instantly in the result box.
- Export: Click "Copy Result" to save the output to your clipboard.
Frequently Asked Questions
How do I convert octal to decimal?
To convert manually, determine the position of each digit starting from 0 on the right. Multiply each digit by 8 raised to the power of its position. Finally, sum all the results to get the decimal equivalent.
How to convert octal to decimal in scientific calculator?
Enter "Base-N" or "Programmer" mode on your calculator. Select Octal (OCT) as the input base and type your number. Then, switch the mode to Decimal (DEC), and the calculator will automatically display the converted value.
How do you convert 514 octal to decimal?
The calculation is: (5 × 8²) + (1 × 8¹) + (4 × 8⁰). This breaks down to (5 × 64) + (1 × 8) + (4 × 1), which equals 320 + 8 + 4. The final decimal result is 332.
What is the octal number 714 to the decimal number?
Expand the number as: (7 × 8²) + (1 × 8¹) + (4 × 8⁰). This equals (7 × 64) + (1 × 8) + (4 × 1). Adding 448 + 8 + 4 results in the decimal number 460.
How do you convert 123 octal to decimal?
Calculate the positional values: (1 × 8²) + (2 × 8¹) + (3 × 8⁰). This simplifies to 64 + 16 + 3. The resulting decimal value is 83.
