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.

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.

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.

The digits must be valid for the source base — for example only 0 and 1 in binary, or 0–9 and A–F in hex. An invalid digit makes the result undefined.

They are single digits for the values 10 through 15: A is 10, B is 11, up to F which is 15. This lets base 16 fit numbers up to 15 into one place before it has to carry.

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.
