Spring Constant Calculator

Calculate the spring constant using Hooke's law k = F/x. Enter force and displacement.

How to Use the Spring Constant Calculator

  1. Enter the force applied to the spring in newtons.
  2. Enter the displacement (stretch or compression) in meters.
  3. Click Calculate to find the spring constant and stored energy.

Formula

k = F / x, where k is the spring constant (N/m), F is force (N), x is displacement (m). Energy = ½kx².

Domande Frequenti

What is Hooke's law?
Hooke's law states that the force needed to extend or compress a spring is proportional to the displacement: F = kx.
What are typical spring constant values?
Ranges from ~1 N/m for soft springs to >100,000 N/m for stiff industrial springs.
