Front springs

Everone seems to be talking about springs so here's my two-penneth.
1) does anyone recognise 1.9 12/60 written on the top of some plus2 front springs picked up recently?
2)is it as simple as putting a weight( myself-169 pounds)on the spring,measuring the compression and then equating that to the rate in pounds per inch?
Thanks
John

I dont recognise the code but it probably relates to free length, wire diameter and working coils.
To determine spring rate easiest to get the bathroom scales and measure the load on the scales as you compress the springs to various lengths.
The spring formula F= k x L can then be determined at a number of points and k should be close enough to constant at all measurement points for a normal constant rate spring
F = force lb
k = spring rate lb /inch
l= amount of spring compression inch

That sounds safer than "I'll just pop these engine parts in the dishwasher while SWMBO is away on a business trip for a week"
- just as well it was a week though as it took that long to clean it and get rid of the oil smell.

Well,the 1.9 could be the I.D. of the spring,but as for the number of turns 16

P.S.
And you should of seen the smile on her face after roasting the chicken (not long after i'd put half a m/cycle crankcase in the oven to release a bearing) it wasn't quite as good as castrol R but then you can't have everything can you!!!!

A little tip - you can get dishwasher cleaner & de-odouriser packs which clear away the oily smells & residues a treat! She will never know. Works brilliantly with spanners & socket sets as well.
I thought I was the only one.......!
