A binary, hex and decimal converter shows the same whole number across number bases. Computers ultimately work in binary (base 2), but programmers routinely switch between bases to make values readable: decimal (base 10) for everyday quantities, hexadecimal (base 16) for byte values and memory addresses, and octal (base 8) for things like Unix file permissions. This converter takes a whole number in any of those four bases and shows it in all four at once, along with its bit length. The digits allowed in each base go up to one less than the base — binary uses 0–1, octal 0–7, decimal 0–9 and hex 0–9 then A–F for 10–15 — and the tool rejects digits that are out of range for the base you pick.
As a worked example, the decimal value 255 is FF in hexadecimal, 377 in octal and 11111111 in binary — eight bits all set, i.e. exactly one byte at its maximum. To convert decimal to hex by hand you repeatedly divide by 16 and read the remainders from last to first; the calculator does it instantly and also accepts input prefixed with 0x (hex), 0b (binary) or 0o (octal) and handles negative numbers.
The reason hexadecimal is so common in computing is that each hex digit maps to exactly four binary bits (a nibble), so two hex digits describe one byte with no ambiguity — which is why colour codes like #FF8800, MAC addresses and memory dumps are written in hex. This tool is handy for bit masks, colour values, debugging register contents and any low-level work where you need to see the same number across bases.

Kodi ndingasinthe decimal kuti hexadecimal?
Repeatedly divide by 16 and read the remainders from last to first, using A–F for 10–15. Decimal 255 is FF in hex and 11111111 in binary.
N’chifukwa chiyani hexadecimal amagwiritsa ntchito mu computing?
Each hex digit maps to exactly four binary bits, so hex is a compact, readable way to write byte values and memory addresses — 0xFF is one byte of all ones.
Kodi ndingapezepo mawerengero ndi 0x, 0b kapena 0o prefixes?
Ndiko. Kuyambira 0x (hex), 0b (binary) kapena 0o (octal) prefix ndi kuthetsedwa mwamsanga, kotero inu mukhoza kukoka mfundo mosalekeza kuchokera ku code. Just onetsetsani mkati mwa base inu kusankha kugwirizana ndi digits inu analemba.
Kodi ndi chiyani bit m'lifupi anganene ine?
Ndi kuchuluka kwa digits binary ndalama amafuna. Decimal 255 ndi 8 ma bits (one byte); 256 amafuna 9 ma bits. Bit m'lifupi ndi zothandiza kwa kusankha data mitundu ndi kuyeza ngati ndalama amagwirizana mu byte, 16-bit mawu kapena 32-bit bungwe.
Kodi octal amagwiritsa ntchito chiyani?
Octal mabungwe ma bits mu threes ndi amasonyeza pamwamba kwambiri mu Unix fayilo ufulu (monga 755 kapena 644) ndi ena legacy machitidwe. Mmodzi octal digito mapu kwa moyenera atatu binary ma bits, mmene mmodzi hex digito mapu kwa awiri.
N'chifukwa chiyani ndinali "invalid mnda kwa izi base"?
Zina la digito lomwe mwalemba sililoledwa m'maziko osankhidwa - mwachitsanzo, dzina la F kapena zina la digito 8 m'maziko a binary, zomwe zimaloleza 0 ndi 1. Sinthani maziko olemba kuti azigwirizana ndi mfundo yanu, kapena chotsani zina la digito lopanda malire.
