O ovom kalkulatoru
A number base converter rewrites an integer from one positional base to another — binary (base 2), octal (base 8), decimal (base 10) and hexadecimal (base 16). It reads your value in the source base, works out its plain decimal value, and re-expresses that value in the target base.
Each base uses a fixed set of digits: 0–1 for binary, 0–7 for octal, 0–9 for decimal and 0–9 then A–F for hexadecimal, where A–F stand for 10–15. Because 16 is 2⁴, each hex digit maps to exactly four binary digits, which is why programmers use hex as shorthand for raw bytes.
Worked example: the decimal number 255 is 11111111 in binary and FF in hexadecimal, since 255 = 15×16 + 15. The converter also reports the intermediate decimal value so you can check the working. A results table shows the same number in all four bases at once, and an invalid digit for the chosen source base is flagged rather than silently miscounted.
Često postavljana pitanja
Kako da pretvorim decimalni u binarni?
Repeatedly divide by 2 and read the remainders from bottom to top. For example 10 in decimal is 1010 in binary, and 255 is 11111111.
Za šta se koristi heksadecimalni sistem?
Hexadecimal (base 16) packs four binary bits into one digit (0–9 then A–F), so it is a compact way to write bytes. The decimal number 255 is FF in hex.
Zašto moj broj pokazuje crticu?
Cifre moraju biti važeće za izvornu bazu - na primjer samo 0 i 1 u binarnom sistemu, ili 0-9 i A-F u heksadecimalnom sistemu.
Šta slova od A do F znače u heksadecimalu?
Oni su pojedinačne cifre za vrijednosti od 10 do 15: A je 10, B je 11, do F koji je 15. Ovo dopušta bazi 16 da stane brojeve do 15 na jedno mjesto prije nego što mora nositi.
Zašto je svaka heksadecimalna cifra jednaka četiri binarne cifre?
Because 16 equals 2 to the fourth power, every hexadecimal digit covers exactly four bits. So the byte 11111111 groups into 1111 1111, which is FF — this number base converter does that grouping for you.
Može li ovaj konverter da obradi veoma velike brojeve?
It works on whole numbers and is accurate up to the range integers are stored exactly (about 9 quadrillion, or 2⁵³). Beyond that, extremely long binary or hexadecimal strings may lose precision in their last digits.
