Spring Rate Converter
Enter your spring rate in lb/in or kg/mm and have it automatically converted.
Not every manufacturer lists their spring rates in both units so a converter can be handy when comparing options.
If you’d like to convert rates yourself:
- kg/mm / 55.88 = lb/in
- lb/in * 55.88 = kg/mm
