Use this hex to decimal converter to turn any hex value into base ten.

Why Use Our Hex to Decimal Tool?

This tool serves students, developers, and curious readers with fast results.

• Simple input with instant conversion as you type.
• Accepts values with or without the number sign.
• Works with uppercase or lowercase letters.
• Runs on Enter and with the Convert button.
• Shows clear messages for input errors.

How the Tool Works

Hexadecimal uses base sixteen with digits 0 to 9 and letters A to F.

Each position holds a place value that grows by sixteen each step.

For example, 2A equals 2 times 16 plus 10, which equals 42.

• Input box: enter only hex characters 0 to 9 and A to F.
• Prefix support: add a number sign if your value includes it.
• Case handling: use uppercase or lowercase, both work.
• Prefix note: use plain hex digits, skip the 0x prefix.
• Conversion triggers: press Enter or click Convert.
• Empty input clears the results area.

Here is what the results show after conversion.

• Hexadecimal: your input shown in uppercase.
• Decimal: base ten value with digit grouping based on your browser.
• Binary: base two value for quick checks.
• Octal: base eight value for legacy systems.

Notes and limits to keep in mind.

• Enter continuous characters only with no spaces.
• Letters must be A to F, any other letter triggers an error.
• Very long values over 13 hex digits can reduce accuracy thanks to JavaScript number limits.
• Examples within the tool match the actual conversion logic.
