# Hex Converter > Convert between Decimal, Hexadecimal, and Binary formats. **Category:** Conversion **Keywords:** base16, math, developer, hex, binary, decimal **URL:** https://complete.tools/hex-converter ## How it calculates The conversion between hexadecimal and decimal utilizes the following formulas: 1. To convert hexadecimal (H) to decimal (D): D = Σ (digit × 16^position) where 'digit' is each hex digit and 'position' is its positional index (starting from 0 on the right). 2. To convert decimal (D) to hexadecimal (H): H = D ÷ 16, with the remainder determining the hex digit. The conversion from hex to decimal involves summing the product of each digit and 16 raised to its positional index. For decimal to hex, repeated division by 16 yields the hex digits in reverse order. This ensures every hexadecimal digit corresponds accurately to its decimal representation and vice versa. ## Who should use this 1. Software developers converting color codes from hexadecimal to decimal for graphic design applications. 2. Data analysts interpreting hexadecimal memory addresses in debugging processes. 3. Computer scientists studying numerical systems in algorithm design. 4. Electronic engineers converting binary-coded decimal values to hexadecimal in circuit design. 5. Game developers managing hexadecimal values for graphics and rendering settings. ## Worked examples Example 1: Convert the hexadecimal number '1F' to decimal. - '1F' = (1 × 16^1) + (15 × 16^0) = 16 + 15 = 31. Therefore, '1F' in decimal is 31. Example 2: Convert the decimal number '255' to hexadecimal. - Divide 255 by 16: 255 ÷ 16 = 15 remainder 15. - The quotient 15 corresponds to 'F' in hex. - Thus, 255 in hexadecimal is 'FF'. Example 3: Convert '2A3' from hexadecimal to decimal. - '2A3' = (2 × 16^2) + (10 × 16^1) + (3 × 16^0) = 512 + 160 + 3 = 675. So, '2A3' equals 675 in decimal. ## Limitations 1. The tool may not handle extremely large hexadecimal values accurately due to precision limits in floating-point representation. 2. Hexadecimal numbers with invalid characters (e.g., G, H) will produce errors, as the tool assumes valid input. 3. The conversion from decimal to hexadecimal is limited to integers; decimal fractions are not processed, leading to potential inaccuracies in such cases. 4. The tool does not support negative values; entering negative hexadecimal or decimal numbers could yield incorrect results. 5. It assumes users have a foundational understanding of numeral systems, which may not be the case for all users. ## FAQs **Q:** How does the Hex Converter handle large hexadecimal numbers? **A:** The Hex Converter processes large hexadecimal numbers through standard algorithms, but may encounter precision issues due to floating-point limitations in representing very large integers. **Q:** Can the Hex Converter convert negative numbers? **A:** No, the Hex Converter is designed for non-negative integers only; negative hexadecimal or decimal numbers are not supported. **Q:** What happens if I input an invalid hexadecimal digit? **A:** The tool will return an error message indicating an invalid input, as it only accepts the characters 0-9 and A-F for hexadecimal values. **Q:** How can I convert a fractional decimal to hexadecimal accurately? **A:** The current Hex Converter does not support fractional decimal to hexadecimal conversions; users must convert integers separately from fractions. --- *Generated from [complete.tools/hex-converter](https://complete.tools/hex-converter)*
