Formula
Hex digit = group of four binary bits (e.g. 1101 â D)
Binary = convert each hex digit into its 4-bit binary representation
Decimal conversions use base 2 or base 16 positional notation

Full Description
Binary and hexadecimal are closely related since four binary digits map to a single hex digit. This converter provides a quick way to move between the two, plus a decimal reference that helps check results or integrate with documentation requiring base-10 values.
Programmers often use hex for readability when dealing with memory addresses or bit masks, while hardware manuals may list binary pin states. Having both representations handy speeds up troubleshooting and data entry.
The converter respects negative values by applying the sign consistently across conversions.
Frequently Asked Questions
Does the converter handle fractional values?
It focuses on integers. For fractions, convert the integer part and fractional part separately or use specialized software.
Are lowercase hex values accepted?
Yes. Inputs are normalized to uppercase automatically, and the output is shown in uppercase hex.
What about very large numbers?
Within JavaScriptâs safe integer range, conversions are accurate. Beyond that, precision may degrade.
Can I convert directly between binary and hex without decimal?
Yesâthe tool shows both. Decimal is included purely as a reference to understand the numeric magnitude.
