kg/mm to lbs???
anyone know the conversion factor from kilograms to american spring rates???
toda coilovers sell 8kg front and 6kg rear rate with their coil overs. how much is this to lbs?
i think with the equation, i can find the reverse lbs to kg. and i already tried mutliplyting by 2.2, it doesnt work. casue american spring rates are in the hundreds...

Re: kg/mm to lbs??? (wesuri)
You converted the kg to lb, but you didn't bother converting the mm to inches. There's 25.4 mm to an inch. Anyway, math is hard so I'll have the computer do it.
$ units
500 units, 54 prefixes
You have: kg/mm
You want: lb/in
* 55.997415
/ 0.017857967

Re: kg/mm to lbs??? (wesuri)
It's late, my eyes and brain are fried, but try this: Think in terms of multiplying fractions and do the following (assuming that the small numbers mean they are rating them in kg/mm (8 kilo load compresses the spring 1mm)...
kg/mm x 2.2lb/1kg x 25.4mm/1in = lb/in
OR
(Asian rate) x 2.2 x 25.4
OR
(Asian rate) x 55.8
Your 8kg/mm springs are about 446lb/in and the 6kg/mm springs are about 335lb/in.

OK, tell Mr. K. where he went wrong and you can go to recess early... 
1lb/2.2kg
Off to recess! Yay!

Re: kg/mm to lbs??? (Furry)
normally springs are measured in IN/LB
56in/lb = 1 kgf/mm
56in/lb = 1 kgf/mm

Since I'm playing Units **** tonight, I'll point out that it should be lb/in, not in/lb. (Read "/" as "per.") A Slinky probably stretches 56 inches per pound. I hope your suspension doesn't.
