Nb is the chemical symbol of niobium.

The conversion factor to convert inches to "Nominal Bore" (NB) is 25.4 mm per inch. NB sizes are based on the internal diameter of a pipe, and they do not directly correlate to inches.
1) Nota Bene (Latin: Note Well) 2) Niobium
The electronic configuration of niobium (Nb) in its neutral state is ( [Kr] 4d^4 5s^1 ). When niobium loses four electrons to become Nb(^{4+}), the configuration changes to ( [Kr] 4d^4 ), as the 5s and three of the 4d electrons are removed. Thus, the electronic configuration for Nb(^{4+}) is ( [Kr] 4d^4 ).
NB stands for Nominal Bore.
NB is nothing but Nominal Bore.

"nb" is not a recognised unit of measurement for length and so the question cannot be answered.

I am not quite sure what you mean by "nb", but I don't think it's a unit of length.
I suspect that NB stands for the Latin phrase nota bene,whick means 'note well'.
