Spring rate (also known as the spring constant or stiffness) is a measure of how much force is required to compress or extend a spring by a certain distance. Our Spring Rate Calculator is designed for mechanical engineers, mechanics, and physics students to easily determine the stiffness of a suspension system, mattress spring, or any elastic material.
k = F / x
Where F is the force applied in Newtons, and x is the displacement (change in length) in meters. The result is given in Newtons per meter (N/m).
