Is the spring constant basically the resistive force to the force (F) applied to the spring that make it extend, because people saying it it's a measure of how much for compresses or extends the spring per metre ?
If not can someone explain to me what it is
I know its measured in NM, but I still cannot understand what exactly it is.

The unit of spring constant is N/m and not Nm. Its a ratio that gives you an idea how "stiff" the spring is. Lets take two springs of different 'k's. One is of 1 N/m and the other of 10 N/m. Thus to compress the first spring by 1 m, I need just 1 N which is very easy. On the other hand, the other spring needs me to apply 10 N to deflect the spring by same 1 m, thus becoming 10 times harder than the first spring.

In mechanics, and physics, Hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it. Many materials obey this law as long as the load does not exceed the material's elastic limit. Materials for which Hooke's law is a useful approximation are known as linear-elastic or "Hookean" materials. Hooke's law in simple terms says that strain is directly proportional to stress.
