How do I convert a spring constant of N/cm to N/m

[Waynerds]

Homework Statement

my spring constant is 85 N/cm and I have to convert to N/m

Homework Equations

why does stoichiometry not work on this? How would I approach conversions like this?

The Attempt at a Solution

I tried converting the 85 N/cm to N/m and ended up getting 85*10^2 N/m. This was using basic stoichiometry.

Usually this skill is lumped in with what is called 'dimensional analysis.' Try looking over this link: https://www.chem.tamu.edu/class/fyp/mathrev/mr-da.html and see if you can make some sense of it. Your problem is very similar to the example except you have units of cm in the denominator.

Stoichiometry is what you use to balance chemical reactions.

If it takes a force of 85 N to stretch a spring 1 cm, how many Newtons will it take to stretch the same spring 100 cm (= 1 meter)?
