S.i unit and dimension of angular momentum?

Answer : The SI unit for is ##quad kg.m^2.s^{ -1}## and its dimension is ##M.L^2.T^{ -1}##.
Explanation : Angular Momentum is the rotational motion equivalent of the Linear Momentum of Translational motion. It is defined as the moment of Linear Momentum.
##vec{L} equiv vec{r}timesvec{p}= vec{r}timesmvec{v}##
##L = r.mv.sintheta; qquad sintheta ## is a unitless quantity.
SI units for ##m r## and ##v## are respectively ##kg## ##m## and ##m.s^{ -1}##.
