Look Honey, PrusaSlicer Shrank the Model!

I've been using Fusion 360 and modeling and printing some very simple stuff.  But today for the first time I only wanted the stl file for one component.  But when I imported the stl file into PrusaSlicer the model was barely visible because it was so small.  Here's a screen shot after I enlarged the view as much as possible.  Note the size figures!

I don't see it above but it is there in the screenshot I took!  The sizes are also missing above but here's a more limited screenshot of just the sizes: 

I don't understand why they are in mm.  I was working in inches as I usually do.  If I tell PrusaSlicer to "Slice Now" I get this error popup:

This could well be a Fusion 360 problem but I thought I'd ask here first.

Thanks for any comments you might have.  Bob

RE: Look Honey, PrusaSlicer Shrank the Model!

Just about every slicer works in metric, which means millimetres. Exported stl files do not contain any real world scaling data. You have to make sure that your exports from fusion are in mm. if you don’t you end up with a very tiny model that you have to scale up by iirc 2450%

the next version of Prusa Slicer is supposed to have an automatic scaling option to deal with models that have been done in inches but until then you will have to do it the manual way.
