Binary to Decimal to Hex to Octal Converter โ All in One | CalcNation
Convert between Binary, Octal, Decimal, and Hexadecimal number systems instantly. Supports 8/16/32/64-bit integers, signed/unsigned, two's complement for negative numbers, big/little endian byte order, ASCII preview, popcount (Hamming weight), and IEEE 754 floating point analysis.
How Binary to Decimal Works
Binary (base 2) uses digits 0 and 1. Each bit position represents a power of 2. Example: 11111111โ = 128+64+32+16+8+4+2+1 = 255โโ = FFโโ = 377โ
What is Two's Complement?
Two's complement is how computers represent negative numbers in binary. To negate: flip all bits and add 1. Example: +5 = 00000101, โ5 = 11111011 in 8-bit signed representation.
