nominal bore
Nb is the chemical symbol of niobium.
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.
Nb is the chemical symbol of niobium.

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'.
