If you've seen a chart like this, it was wrong.
I know that's a bold claim, but in general there are better ways to pick a motor than by a comparison to something else. This is mostly because an electric system can be tuned to an airframe much better than an engine can, by varying voltage, Kv, and prop size. With an engine, you're given a size by the instructions and you get to choose 2-stroke or 4-stroke, with a bit of prop selection. It works, but rarely gives the best possible setup because there are so few options.
With electric, it's best to size your motor based on the weight and desired speed of the model. It can be intimidating at first because there are so many hundreds of choices, but with a bit of care it can result in a power system perfectly suited to a particular airplane.
