Objects in STL-file imported to other software are 1/1000 of original size

I use SketchUp for Web to make a STL -file for my 3D printer. When I export the file to any other software (FreeCAD 0.18 & Simplify3D) the object is just 1/1000 of the size shown in SketchUp.

STL files are unitless. The application you are importing them to expects a different modelling unit than the one you have used to model and export in SketchUp. It sounds like you have used Meters but FreeCAD or Simplify are expecting millimeters.
