1 gallon of gasoline contains ~33.7kwh of energy, even if an ICE can usually only extract about 25-40% of that. Let's say an EV has a battery that can hold 33.7kwh exactly, and it can go 80 miles on a charge. That EV has 80 miles per gallon equivalent.
What isn't taken into account is cost - where I live, 33.7kwh of electricity costs about $6, while a gallon of gas only costs about $2.30. Since I can reliably get 70mpg tanks in my Insight, an EV would need to get 2.5x that, or 175MPGe to break even in cost per mile, not taking oil changes and other maintenance into account.
