Frequently Asked Questions
Why does binary convert so cleanly to hex?▾
Each hex digit represents exactly 4 binary bits (since 2⁴ = 16). So you can group binary digits in fours and replace each group directly with its hex digit — no calculation needed.
What is a nibble?▾
A nibble (or nybble) is a 4-bit group — half a byte. Each nibble maps to exactly one hex digit (0–F).
How do I convert FF (hex) to binary?▾
Replace each hex digit with its 4-bit binary: F = 1111, F = 1111 → 11111111 = 255 decimal.
