Conversion Utilities

Hexadecimal To Decimal

Converts hexadecimal values to decimal integers with precise mathematical accuracy. Use via MCP in Cursor or Windsurf for instant base conversion, or call GET /v1/convert/base/hex-to-dec directly. Input "FF" returns 255, "1A3" returns 419. Handles both uppercase and lowercase hex notation without 0x prefix required.

FAQ

How do I convert hex to decimal using MCP in Cursor?

Call the hex-to-decimal tool with your hex value as input. The MCP tool handles the conversion automatically and returns the decimal equivalent.

Do I need to include 0x prefix for hexadecimal input?

No, the tool accepts raw hex values without the 0x prefix. Both 'A1' and '0xA1' work, but the prefix isn't required.

What's the maximum hex value this tool can convert?

The tool handles standard integer ranges. Very large hex values may hit system limits, but typical programming values convert without issues.

Does the converter handle both uppercase and lowercase hex?

Yes, it processes both cases identically. 'ff', 'FF', and 'Ff' all convert to 255.

What happens if I input invalid hexadecimal characters?

The tool returns an error for invalid hex characters. Only 0-9 and A-F (case insensitive) are accepted as valid hexadecimal digits.
