Euro spring rates are in N/mm. Multiply by 5.71 to get lbs/ft http://people.physics.anu.edu.au/~am..._conversio.htm

On the springs is 100 - 160. One will be the spring rate, one the spring free length in mm. I presume 100 is the spring rate and 160mm the length. It could be the other way, 100mm length (although spring looks longer in the pic) and 160 rate (900lb which seems quite high)
