Octal to Decimal Converter

What is Octal to Decimal Converter?

The Octal to Decimal Converter is a free online tool that converts octal (base-8) numbers to decimal (base-10) numbers instantly, with proper calculations. Decimal numbers contain digits from 0-9, while octal numbers only use digits from 0-7. Such conversions are essential in fields like computer science and digital electronics, where different numbering systems are used for data representation and computation.

What is the Octal Number System?

The octal number system is base-8, meaning it only uses digits between 0 and 7. This system is commonly used in computing to make binary representation of large numbers more compact. Since three binary digits (bits) can represent one octal digit, it’s convenient for applications in digital systems and GPIO (General Purpose Input/Output) operations.

For Example:

• In octal, the number “10” represents the decimal number 8.
• Each positional increase (like 1, 10, 100) represents a power of 8, so the second position is 8, the third is 8², and so on.

What is the Decimal Number System?

The decimal number system, also known as base-10, is the most commonly used system in daily life. Decimal digits range from 0 to 9, and each position in a decimal number represents a power of ten. This system is widely used because people have ten fingers, which likely influenced its development.

For Example:

• In decimal, the number “10” represents ten, with each positional increase (like 1, 10, 100) representing a power of 10.

How to Convert Octal to Decimal

To convert an octal number to decimal, each digit is multiplied by 8 raised to the power of its position (starting from the right). Here’s a step-by-step guide:

1. Write down the octal number.
2. Identify the positional values, starting from the rightmost digit as 8⁰, the next as 8¹, then 8², and so on.
3. Multiply each digit by the corresponding power of 8 based on its position.
4. Sum all the values to get the decimal equivalent.

For Example: Convert the octal number “125” to decimal.

• 1 × 8² = 64
• 2 × 8¹ = 16
• 5 × 8⁰ = 5
• Total = 64 + 16 + 5 = 85

So, the octal number "125" is "85" in decimal.
