Inkscape svg problems (wrong size) when imported to fusion

I am saving as a “plain SVG”
I am using Inkscape 92.4

When I draw in Inkscape I currently use inches
In Fusion the units are either metric or standard.

I will keep playing around but I am still kind of lost why some SVG files are perfect but the ones I create in Inkscape need to be resized.
I will try to create a file using PPI

Thanks Tim
