    A nanometer is equivalent to 10^-9 meter. While a centimetre is equivalent to 10^-2 meter. Therefore the conversion factors are:

    1 nanometer = 10^-9 meter

    1 centimeter = 10^-2 meter

    So,

    0.227 nanometer * (10^-9 meter / 1 nanometer) * (1 centimeter / 10^-2 meter) = 2.27 x 10^-8 centimeter

    Answer:
