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.
Takon kang asring diajukake
Kepiye aku bisa ngowahi desimal dadi hexadecimal?
Ing taun 1996, dhèwèké diwènèhi gelar Ph.D. ing bidang filsafat lan sastra, lan ing taun 2000 dhèwèké diwènèhi gelar Ph.D. ing babagan filsafat lan sastra.
Apa tegesé heksadesimal ing komputer?
Saben digit hex dipérang dadi papat bit biner, saéngga hex iku cara sing kompak, bisa dibaca kanggo nulis nilai byte lan alamat memori — 0xFF iku siji byte saka kabeh.
Apa kula saged nyerat angka kaliyan prabédan 0x, 0b utawi 0o?
Ya. Prefiks 0x (hex), 0b (binary) utawa 0o (octal) dicopot kanthi otomatis, supaya sampeyan bisa nyelehake nilai langsung saka kode. Mung priksa manawa basis input sing sampeyan pilih padha karo digit sing sampeyan ketik.
Apa kang dadi sebabé?
Iki ya iku jumlah digit biner kang dibutuhaké kanggo nilai. Decimal 255 iku 8 bit (siji baité); 256 butuh9bit. Jarak bit bisa digunakake kanggo milih jinis data lan mriksa yèn nilai bisa disimpen ing baité, tembung 16- bit utawa register 32- bit.
Apa kang dadi tujuané?
Octal nglumpukaké bit ing tiga lan katon utamané ing hak akses Unix (kaya 755 utawa 644) lan sawetara sistem legacy. Saben digit octal ngemot telung bit biner, cara saben digit hex ngemot papat.
Mengapa aku nampa "nomor ora valid kanggo basis iki"?
Digit kang sampeyan ketik ora diijini ing basis kang dipilih - contoné huruf F utawa digit 8 ing angka biner, kang mung ngidini 0 lan 1. Ganti basis ketik supaya padha karo nilai sampeyan, utawa ngganti digit kang ora ana ing njero watara.
API — gunakake kalkulator iki saka kode
Panggenan kalkulator iki minangka titik pungkasan JSON gratis - ora ana kunci sing dibutuhaké. Kirimi nilai medan ing ngisor iki minangka parameter pitakonan utawa JSON. Anything you omit uses the same default this page is pre-filled with; an unknown parameter is a 400, never a silent zero. Waca dokumen API lengkap →
