You can currently do:

Units<double>::Acceleration  gravity(9.81);
Units<double>::Acceleration  my_acc(2.0);
Units<double>::Dimensionless d1;
double                       d2;

d1 = my_acc / gravity;

d2 = value(my_acc/gravity);

How do people feel about implicit conversion to allow:

d2 = my_acc / gravity;

or

d1 = 5.0;
