The rate or spring constant of a spring is the change in the force it exerts, divided by An extension or compression spring has units of force divided by distance, law which states that the force a spring exerts is proportional to its extension.

The extension of a spring is in direct proportion with the load added to it as long as this load does not exceed the elastic limit.F = -kxwhereF is the restoring force exerted by the material (in SI units: N);x is the displacement of the end of the spring from its equilibrium position (in SI units: m);k is the force constant (or spring constant) (in SI units: NÂ·m-1 or kgs-2).

That is called the Spring Constant. It describes the amount of deformation of the spring, either stretch or compression, in units of distance deformed for each unit of force applied.

Mathematically, Hooke's law states that: F = -kx, Where, x is the displacement of the end of the spring from its equilibrium position (in SI units: "m"); F is the restoring force exerted by the material (in SI units: "N" or kgms-2); and k is the force constant (or spring constant) (in SI units: "N·m-1" or "kgs-2"). 　 　

Not knowing what units you are using (is that newtons per meter? pounds per inch? gram-force per micron?), and what type of spring you are talking about, little can be said about that.

Hooke's law is not related to any "natural length". Rather, it defines a string constant: how much the string extends or compresses, depending on the applied force. In SI units, the spring constant would be measured in newton/meter.

The formula is F = kx, so solving for "k", you get k = F/x; in other words, a force divided by a distance. In SI units, you would use newtons / meter.

The units are m-1 or per metre.

Hooke's Law can be stated as:F = -kxWhere x is the displacement, k is some constant, and the negative sign means that the force is in a direction opposite to the displacement.Solving for the constant k gives:k = -F/xIn SI, this would give it units of Newton / meter, but any other convenient unit can be used, for example, Newton / centimeter.
