Can someone please convert these spring rates: 400 (front) and 225 (rear). I'm used to seeing spring rates, for example, in the format of 10 (front) and 8 (rear). I'm assuming my numbers are based on lbs/inch as opposed to kg/mm. Thanks.

 

To convert from SI unit (kg/mm) to English unit (lbs/in), multiply 55.88.

Divided by 55.88 if you want to go the other way. So in your case, it's 7.16 kg/mm front, 4.03 kg/mm rear.

 

I've been using 56 as specified here (first paragraph):

Although this is probably more precise:

If we use 56, that means 400/56 and 225/56 = 7.14F / 4.01R.

I'm not sure if these values are supposed to be rounded to a whole number or if it's customary to go to 2 decimal positions (or maybe only 1 decimal position?).

 

BTW, if you're running Windows and want a nice little utility to handle other types of basic convertions, this is what I use:

or just put "400lbs/inch to kg/mm" in google

 

Thanks you guys
