Helical Compression Spring Calculator

Calculate spring constants and compression forces from material properties and physical dimensions. Solves the problem of AliExpress spring listings that show wire diameter, coil count, and material but not the actual spring performance you need for mechanical design.

More tools coming soon. Each tool is designed to solve specific problems I’ve encountered in projects, with a focus on practical utility over feature completeness.
