    Distance per volume (mpg or km/L) is kind of a lousy way to reason about fuel economy; a better system is to take the reciprocal: gallons per mile, or liters per km.

    (Here's an accessible argument for why: https://www.popsci.com/technology/gallons-per-100-miles-best-fuel-economy-metric/)

    But volume / distance = length³ / length = length² = area. That means we can measure fuel economy using area.

    For example, my car gets about 0.08mm². That’s not a rate. It’s just an area (in the rough vicinity of the period at the end of this sentence).

    Huh?
