How much/small is a nano?

Is it right to use either much and small in the above? Thanks.

    We don't really have a context :). But since it's most likely you're asking about size, then "how small" is correct.

    So, since nano is a prefix (thank you, JulianStuart) and does not really describe a 'thing / object', it does not have a size, does it?
