In reply to: Let's assume the 65 number from the article is indeed posted by G.K.Chesterton
The ChatGPT explanation states that the MPGe calculation is made by taking range divided by battery capacity times the conversion factor:
From your post
3. **MPGe Calculation**: To calculate an EV's MPGe, the EPA divides the distance an EV can travel on a fully charged battery (in miles) by the energy content of the electricity (in kWh) used to charge the battery, and then multiplies this number by the fuel-content factor of 6.67. This provides a miles per gallon equivalent that can be compared to gasoline vehicles
I don't know if ChatGPT is correct, but it is explicit that MPGe is calculated with the 6.67 factor.
So is the multiplier irrelevant or not?
Of course, it's explanation of how the 6.67 comes about makes no sense mathematically, so it's explanation here could make no sense as well.
either. I think since I asked the question, it tried to make sense of it. And failed. My bad for using it in my retort.
After endless Google searches and ChatGPT queries, the 6.67 multiplier has no bearing on anything and seems to be spun out of whole cloth.
Bottom line is that nobody uses the Oped writer’s methodology in computing MPGe.
