# Is displacement vector fundamental or derived quantity?

We know that we have 7 fundamental quantities (all scalars) and length is one of them. I classify velocity as a derived quantity. What about a position displacement vector? How do I classify displacement vector. Is it fundamental or derived quantity?

$$[D] = [\epsilon_0]\cdot [E] = [\epsilon_0]\cdot [F]/[Q] = \mathrm{\frac{A^2\, s^4}{kg\, m^3}\cdot \frac{kg\, m}{s^2}\cdot \left(A\, s\right)^{-1} = \frac{A\, s}{m^2}}.$$
$$[r] = \mathrm m.$$
