How to make two objects the same size?

When I import an object from a CAD software such as Blender it sometimes appears bigger or smaller than what I expect it to. For example, an object with a local scale of a can be 10 times bigger than a cube with the same scale. Is there any code with which I can program my object to be the same size as another?

Try setting the size in the inspector part of the projects folder of the object to something bigger. What I mean is go to your projects folder. Clicking your object. Change the size from there in the inspector. Try that.
