Dimensional Analysis of Reciprocal Mass

The mechanical quantity, which has dimensions of reciprocal of mass (\(\text{M}^{-1}\)) is

Torque

Gravitational constant

Angular momentum

Coefficient of thermal conductivity

The dimensions of the Gravitational constant \(G\) are \([\text{M}^{-1}\text{L}^3\text{T}^{-2}]\). Thus, it has the dimensions of reciprocal of mass.
