• ### Spring Constant Calculator

Spring constant is the amount of force required to move the spring a set amount of distance. The set amount of distance is determined by your units of measurement and your spring type. For example if you are calculating the spring constant of a compression spring using English measurements your value would be pounds of force per inch of distance traveled. If you are using the metric system
