To convert kg/mm to lb/in you divide by .0179
To convert lb/in to kg/mm you multiply by .0179

Ex 9kg/mm = ~500 (502.79 lb/in), 8kg/mm = ~447lb/in (446.927), and so on

Ex 1000lb/in = ~18kg/mm (17.9), 800lb/in = ~14kg/mm (14.32)

I think you'll find that multiplying some number by 25.4 and then multiply that result by 2.2046 will give results that are eerily similar to dividing that same original number by 0.0179. I don't know why the manufacturer(s?) would rather divide, but that does not make the other approach wrong (as implied).

Most of the time, I just use 'convert.exe' with a custom kg/mm ←→ lb/in function and the appropriate conversion entered (either 55.9974 or 0.01785797), enter the number I wish to convert, which way I'm running the conversion, and let the program sort it out.

Anymore, I just use 'convert.exe' with a custom kg/mm ←→ lb/in function and the appropriate conversion entered (either 55.9974 or 0.01785797), enter the number I wish to convert, which way I'm running the conversion, and let the program sort it out.

One step vs two is my guess. Less rounding error as well (simply from it being a single step)

i dont mean to sound like an idiot, but

Nissan Maxima Ksport Coilovers - Kontrol Pro Kit
: Spring Rates
Front - 9/504
Rear - 7/392

does this mean there is 9 inches of travel in the front at 504 lb per inch? or what im really kinda lost with this one, cause i dont see this used in what you guys were talkin about

Anybody knows if the front shocks/struts are different for GLE, SE and GXE?

Are there any numbers out there for 6th gen SL and SE? I have a 2005 SL and I just got the idea of switching to SE springs. I like the ride height as it is but a bit less lean in corners would be nice. Also does the SE suspension tune include stiffer bushings or a thicker rear sway etc? Thanks in advance. I'm just learning my way around the forums, I've had the Max for less than 2 months.
