📏 Understanding Binary and Octal

Binary Number System (Base-2):
The binary system is the fundamental language of computers. It uses only two digits — 0 and 1 — to represent all forms of data. Every image, video, file, or application on a computer is stored as binary code.
Example: 10102 = 10 (decimal)

Octal Number System (Base-8):
The octal system uses eight digits: 0, 1, 2, 3, 4, 5, 6, and 7. It is commonly used in digital electronics, computer programming, and networking, as it provides a shorter representation of binary numbers.
Example: 128 = 10 (decimal)

👉 Conversion Relationship:
Each octal digit corresponds to 3 binary digits (bits).
1012 = 58

⚖️ Formula / Method to Convert Binary to Octal

  1. Group the binary number into sets of 3 bits (from right to left).
  2. Convert each group of 3 bits into its equivalent octal digit.
  3. Combine the octal digits to form the final number.
Example:
1101012 = (110)(101) = 658

Our Binary to Octal Calculator applies this method instantly, eliminating the need for manual grouping and reducing the risk of errors.

📚 Examples of Binary to Octal Conversion

Example 1:
Convert 1012 to octal

Group: 101
Octal: 58

✅ So, 1012 = 58

Example 2:
Convert 1110002 to octal

Groups: (111)(000)
Octal: 708

✅ So, 1110002 = 708

Example 3:
Convert 10011012 to octal

Pad to 9 bits: 001 001 101
Groups: (001)(001)(101) → (1)(1)(5)
Octal: 1158

✅ So, 10011012 = 1158

Example 4:
Convert 111111112 to octal

Pad to 9 bits: 000 111 111 111
Groups: (111)(111)(111) → (7)(7)(7)
Octal: 3778

✅ So, 111111112 = 3778

Example 5:
Convert 10101010102 to octal

Pad to 12 bits: 001 010 101 010
Groups: (001)(010)(101)(010) → (1)(2)(5)(2)
Octal: 12528

✅ So, 10101010102 = 12528
