I'm totally confused.
I have a cabinet door to open. I bought a newton scale and it takes 15 newtons to open the door. Unfortunately all the items I've been looking at to do it are by weight (which I can get and understand) or by something like :3.0kg.cm(41.66oz.in).
How does :3.0kg.cm(41.66oz.in) relate to the newtons?
Thanks
Scott
