Reading bit fields
Translate binary register or flag values into the hex constants your code compares against.
Frequently Asked Questions
- How does binary map to hexadecimal?
- Every 4 binary bits equal exactly one hex digit — 1111 is F, 1010 is A. The tool strips whitespace, groups the stream into 4-bit nibbles, and converts each, so 11111010 becomes FA.
- What if my binary length is not a multiple of 4?
- The final short group is parsed with fewer bits, which can shift the intended value. Pad the stream with leading zeros to a multiple of 4 for exact results. Need the reverse direction? Use Hex to Binary.
- What is the full binary-to-hex table (0-15)?
- 0000=0, 0001=1, 0010=2, 0011=3, 0100=4, 0101=5, 0110=6, 0111=7, 1000=8, 1001=9, 1010=A, 1011=B, 1100=C, 1101=D, 1110=E, 1111=F — every possible 4-bit nibble mapped to its single hex digit. This tool applies the same table to however many nibbles your input has.
- Is my data private when I use this tool?
- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
