It is like calling British currency pound sterling because it was once based on the wight of sterling silver.
What you pay in transaction fees is the amount of bytes used to represent your data.
Byteball can then also store immutable data of various lengths, if you are willing to pay for it in the price of bytes for the storage of bytes you like to store.
Miles is a unit of measure, ultimately meters in the SI. A gallon is a volume, liters in the SI, or more fundamentally a fraction of cube-meters (m^3).
m / m^3 = 1/m^2
Which is the unit for fuel efficiency. It's expressed in imperial units but it's physically sound, not 'crap'. ;)
In other parts of the world you'll see this expressed as "liters per 100km" usually.
MPG is more pervasive than you might think. Even in metric, European Ireland it's the typical unit, despite speeds being in km/h and fuel being sold by the litre.
Since you seem to be interested, let me also add that litres are only accepted by, not part of, the SI. Also the SI spellings are "metre" and "litre".
Ha sorry I indeed failed to catch your irony... My bad too, then.
I'm actually quite interested in the fact that any equation can be "sanity checked" by solving it for units only (without values). It's always handy to make sure I didn't forget some exponent here or there. And knowing extended units as a composition of fundamentals (some variation of mksa) is kind of entertaining intellectually.(e.g. Newton = m.kg/s^2, which really makes sense when you think about it). Going down to Planck units and their significance in this universe (discrete spacetime manifold? Is reality ultimately non-continuous?), and here I am wishing our conventional units (of time, distance, all) were integer multiples (e.g.
Decimal exponents) of Planck units. But I'm digressing, aren't I.
As far as fuel and efficiency goes, I'm not much of a car person. I didn't know that mpg was used outside the US, that's an interesting historical artefact.
