Would I be right in thinking that VG 110 oil would be equal to 100cSt ... is it a straight swap or is there any formula. I'm trying to determine the dynamic viscosity

I believe VG110 would be an unusual grade. Typically, when referencing an ISO 3448 grade, the value for the nominal kinematic viscosity (in mm2/s) is given, so the minimum kinematic viscosity is 100 mm2/s. 1 cst = 1 mm2/s

The dynamic viscosity is simply the product of the density and kinematic viscosity, i.e., μ = ρ ν.

Does one know the specific gravity of the oil?
