The dimension of the ratio of angular to linear momentum is
${M^0}{L^1}{T^0}$
${M^1}{L^1}{T^{ - 1}}$
${M^1}{L^2}{T^{ - 1}}$
${M^{ - 1}}{L^{ - 1}}{T^{ - 1}}$
The dimension of the ratio of angular to linear momentum is
$\frac{{{\rm{Angular\, momentum}}}}{{{\rm{Linear\,momentum}}}} = \frac{{mvr}}{{mv}} = r = [{M^0}{L^1}{T^0}]$
