cross converting between classes in c++

I have a class

class Cartesian
{
    float x,y,z;
 };

and another class

class Spherical
{
    float rho, phi, r;
};

How would I convert between them? I have tried adding Spherical Cartesian::toSpherical and Cartesian Spherical::toCartesian inside of the class declarations but no matter the order I put them in, the first one complains that the other one is undefined. I have tagged VS and Ubuntu because I want it to work for both.

Do the forward declaration.

    class Spherical;
    class Cartesian 
    { 
       float x,y,z;
       Spherical toSpherical();
    };

    class Spherical
    { 
       float rho, phi, r; 
       Cartesian toCartesian();
    };
