What is the formula for Spring Force Calculator (Hooke's Law F=kx)?

Core formula: F = k·x. The tool returns results instantly using this formula and the selected parameters.

What engineering notes should I keep in mind when using Spring Force Calculator (Hooke's Law F=kx)?

Hooke's law F = kx: within the elastic limit, force is proportional to deformation and always points toward the natural length. k is the spring constant, in N/m or N/mm (1 N/mm = 1000 N/m); larger k means a stiffer spring. Beyond the elastic limit the spring deforms permanently and Hooke's law no longer applies; series/parallel springs have their own equivalent-stiffness formulas.
