what unit is inertia measured in
A kilogram square centimeter (kgÂ·mmÂ²) is a decimal fraction or the derived unit of moment of inertia in the SI system kilogram square meter. One kilogram square centimeter is equal to the moment of inertia of a single particle having the mass of one kilogram rotating at one millimeter distance from the rotation axis.ram centimeterÂ². A gram square centimeter (gÂ·cmÂ²) is a derived unit of moment of inertia in the CGS system. It is equal to the moment of inertia of a single particle having the mass of one gram rotating at one centimeter distance from the rotation axis.
