FYI, for anyone who works in Imperial inches like me: When I export STL from Blender with a scale of 1000, it is right on the money in Cura. If I export a mesh that is 2.105" in Blender, I can be confident that my digital caliper will read 2.105" of my print. Cura displays mm of my meshes (haven’t found way to change), but an inch to millimeter conversion confirms accuracy. Hope that helps any USA folks (anyone else who works in Inches) new to Blender > Cura > 3D Printer workflow.
Edit: I tend to print very small things, so I might have had to change to this method, to get them to import into Cura… either way, I just go with this and it works every time, no matter how big or small my prints are to be.
