About Reference Tables
Sometimes you need to scan a whole range of values rather than convert one at a time. This category provides lookup tables for hex, decimal, binary, and ASCII values, for exactly that case.
Frequently Asked Questions
When should I use a table instead of a converter?
When you need to see a whole range at once — like every byte value 0-255 — rather than convert a single number.
What's on the ASCII hex table?
Every standard ASCII character alongside its hex and decimal code, useful for reading raw byte dumps.
Is there a combined hex, decimal, and binary table in one place?
Yes — the Hexadecimal Table lists all three side by side for every value 0-255, so you don't need to cross-reference separate decimal and binary tables.
Why would I need a table instead of just using a calculator every time?
Scanning a table is faster than converting one value at a time when you're memorizing common values, checking several bytes in a row, or just want a visual reference open while reading a hex dump.
