Why pair hex with binary?
One hex glyph always maps to four deterministic bits—that makes shorthand memory dumps readable while still aligning with TTL tables and FPGA bitstreams. Translating batches here keeps datasheet masks and microcontroller registers consistent without hand expansion errors.
Teaching workflow
- Keep Auto mode for succinct positive constants.
- Select 4/8/16/…presets so every pupil's waveform lines up.
- Enable two's complement when binary rows represent signed cores.

Frequently asked questions
How do I convert hex to binary?
Expand each hexadecimal digit into four corresponding bits—or paste rows here so the nibbles synchronize automatically line by line.
Do I always need a fixed bit width?
Width presets are optional. Auto removes redundant leading zeros, while widths enforce uniform vector lengths typical in labs.
What does two's complement mean when decoding binary to hex?
With a nonzero width constraint, flipped rows read as CPU-style negatives before emitting their final 0x form.
Can hexadecimal include 0x and underscores?
Yes—both readability helpers sanitize away before arithmetic runs.
