Halving number of coils doubles spring rate.

K = (G * d^4) / (8 * N * D^3)

K is stiffness
G is material shear modulus
d is wire diameter
N is number of active turns or coils
D is mean spring diameter

No. It is not that simple. As Dan said the number of coils is only one part of the equation. You can not simply ignore all the other required data and go by number of coils.
