💡 How Base Conversion Works

Other Base to Decimal: Multiply each digit by its positional weight (powers of the base) and sum the products (e.g., $101_2 = 1 \times 2^2 + 0 \times 2^1 + 1 \times 2^0 = 5$).
Decimal to Other Base: Repeatedly divide the decimal number by the target base and write down the remainders in reverse order.
