At my school, we use the 0-100 scale, to which I have a 95.00 (weighted) GPA. I’ve seen conflicting conversions to the 4.0 scale. Would it be a 4.0, or something more specific such as 3.8?
For application purposes, you report on the 100 point scale. If you want to convert for giggles, here’s one:

Note that you have to convert course by course; you can’t simply convert the final average.
