What is Dimensional Formula of Specific volume?

Specific volume is defined as volume per unit mass of fluid. Specific volume is reciprocal of mass density.

Mathematically,
Specific volume = volume of fluid / mass of fluid.

Dimensional formula of volume = M⁰L³T⁰
Dimensional formula of mass = M¹L⁰T⁰

Putting this value in the above equation we get,

Dimensional Formula of Specific volume= M^-1L³T⁰.
SI unit of Specific volume  is m³/kg .
