Octal to Hexadecimal Converter Calculator
The octal (base-8) and hexadecimal (base-16) systems are widely used in computer science to simplify binary values. This tool allows you to convert any valid octal number into its hexadecimal representation.
How Octal and Hexadecimal Work
Octal uses digits from 0 to 7. It simplifies binary by grouping three bits.
Hexadecimal uses digits from 0 to 9 and letters A to F. Each digit corresponds to four binary bits.
Example: Octal
Step 1: Convert to Decimal → 1×8² + 5×8¹ + 7×8⁰ = 111₁₀
Step 2: Convert to Hex → 111₁₀ = 6F₁₆
157₈Step 1: Convert to Decimal → 1×8² + 5×8¹ + 7×8⁰ = 111₁₀
Step 2: Convert to Hex → 111₁₀ = 6F₁₆
Conversion Method
- 1. Convert the octal number to decimal.
- 2. Convert the decimal number to hexadecimal using division by 16.
Example:
