Binary to Decimal
Convert binary numbers to decimal and vice versa with step-by-step calculation display.
Enter binary or use Example.
Each binary digit represents a specific power of two based on its position, the rightmost digit worth one, the next worth two, then four, then eight, doubling with every step left, and adding up the positions where a 1 actually appears is the entire calculation behind converting binary into decimal, straightforward once seen worked out but easy to fumble doing purely in your head. This tool converts binary to decimal and back, showing the actual positional breakdown, each bit's power of two and whether it's a 1 or a 0, rather than just returning a final number with no visible working.
