Default how to convert spring rates?

so i've always wondered this, how do you go about converting lets say an 8k or 10k spring to pounds? is there a formula? i thought it was a simple metric conversion but that didnt work out so well.

why the different scales?

just make sure you put in kg/mm = lb/in after the number.

you're right. found the formula after scrolling a few more pages. didnt show up on my previous searches.

for anyone else interested:

kg/mm * 56 = lb/in.

Yeah Google calculator is freaking awesome these days.

Just type "12 kg/mm to lb/in" into google and the calculator comes up above all the search results: "12 (kg / mm) = 671.9698975 pound / in"

Edit your text in the search bar and you can try every conversion you want with a click of the return key.
