Hexadecimal to Decimal Conversion Calculator
Hexadecimal numbers (base-16) are often used in computing for their concise representation of binary data. This tool lets you convert hexadecimal values into their decimal (base-10) equivalents with ease.
What is a Hexadecimal Number?
Hexadecimal is a positional number system that uses 16 digits: 0–9 and A–F. Each digit represents a power of 16.
Example: Hex
= 1×16¹ + 15×16⁰ = 31
1F= 1×16¹ + 15×16⁰ = 31
Conversion Method
- Start from the rightmost digit.
- Multiply each digit by 16 raised to the power of its position (starting from 0).
- Add all the results to get the decimal equivalent.
Example: Convert
2×16¹ + A×16⁰ = 2×16 + 10 = 42
2A:2×16¹ + A×16⁰ = 2×16 + 10 = 42
