how do you convert spring rates?

I was given the rates of some springs, both progressive and linear, but they are in N/mm...and I am used to seeing them in KG or #s.

Anyone have a conversion matrix or can direct me to something that can help me translate rates into something I can more understand?

thanks

 

To convert kg./mm. to.......lb./in. ......N./mm.
multiply by ....................55.998........9.807

To convert lb./in. to ......Kg./mm. ......N./mm.
multiply by ................0.017858......0.175133

To convert N./mm. to .......Kg./mm. ......lb./in.
multiply by ...................0.101968......5.7099

Hope that helps.

 

PERFECT....thanks for the prompt reply....I will update my suspension thread with the information I got from Vogtland.

 

All you have to do is break out your trusty web-based converter and have at it...

so
100N = 12.2 KG(force) = 22.5 lb(force)
and 1" = 25.4mm

*USUALLY* when some one says that they have a 100lb spring, they really mean 100lb/in (or what ever that converts to in kg/mm)
HTH.

 

You're welcome, glad I could help. Good luck.
