I was looking through the spring rate chart for various vendors, and thought this might be useful.

1lb = 0.45359237kg
1in = 25.4mm

.45359237 / 25.4 = .017857967322834645669291338582677

So now we know that 1lb/in = .017857967322834645669291338582677.

So if we want a spring that's roughly 560lbs; we'd multiply both sides by 560, and come up with roughly a 10k spring rate. Alternatively if you already know the kg/mm rate and want to find out what the lbs/in is, just divide the spring rate by that reaaally long factoral above (the .0178...).

But just in case you all didn't want to go through all that, here's a chart:

kg/mm to lbs/in
-----------------------------
16 = 896
15 = 840
14 = 784
13 = 728
12 = 672
11 = 616
10 = 560
9.0 = 504
8.5 = 476
8.0 = 448
7.5 = 420
7.0 = 392
6.5 = 364
6.0 = 336
5.5 = 308
5.0 = 280
4.5 = 252
4.0 = 224
3.0 = 168
2.0 = 112

This is handy, you'll have to check the author's math:

Smartass! ; )

If I'd had known it was that easy I wouldn't have done the calculations! But at least it's nice knowing how the calculation is done...
