How It Works
Binary (base-2) uses only two digits: 0 and 1. Each position represents a power of 2, from rightmost (2^0) to leftmost. Decimal (base-10) uses digits 0-9, with each position representing a power of 10. Converting binary to decimal: multiply each bit by its place value and sum. For example, binary 1011 = 1×8 + 0×4 + 1×2 + 1×1 = 11 in decimal. This converter automates this process instantly. Understanding binary is crucial for programming, as all data in computers is stored and processed in binary form. For converting between other units, use our Unit Converter tool.
