Default HPI spring rates???

Anyone know how to convert HPI's spring rates into something more understandable like a losi or associated? I know by color which ones are harder or softer, but I don't know what they rate in pounds.

yo check it!

hpi is in g/mm.
you want lb/in.

take hpi's (???)g/mm x 25.4mm/in x lb/454g.

a.k.a. (hpi) x .056 = lb/in

voila.

Here you have a comparison chart of spring rates from several manufacturers.

The rest of the site is in portuguese, but this particular page is in English
