Work out binary to decimal instantly with clear inputs, formula shown and shareable results.
Each binary digit carries a weight that doubles from right to left, so the value is the sum of 2^position over the set bits. Horner's method accumulates this in one left-to-right pass.
Binary to decimal
value = Σ bitₖ × 2ᵏ, counting positions from the right starting at 0
437, which is 1B5 in hexadecimal.
Two states map directly onto a transistor being on or off, making the electronics simple and robust against noise.
