HEX to Decimal Converter

HEX to Decimal Converter · support unsigned and signed signed bits representation · step-by-step conversions

How it works
Convert in three steps

1. Enter the hex code

Type or paste your base-16 string (0-9, A-F) in the input window.

2. Observe the conversion

The tool processes the hexadecimal string and calculates the base-10 total.

3. Copy the decimal

Save the converted decimal number for your development records.

FAQ
Common questions
No, you can type hexadecimal values using both lowercase (a-f) and uppercase (A-F) letters. The tool automatically standardizes the characters to perform the calculations. This prevents syntax errors during coding entry.
While you can input hex values from color codes (like FF), this tool is built for standard mathematical base conversions. If you want to convert CSS color values, we recommend using dedicated RGB converters.
The tool converts hex values up to a length of 15 characters to stay within safe integer limits (9 quadrillion). Entering hex strings longer than this limit can lead to floating-point rounding errors in the browser.
No, the conversion runs entirely client-side inside your browser session. None of the hex codes, decimal results, or search parameters are sent to servers, keeping your data private.
