> Btw the rest of the world measure temperature in Celsius which is derived from Kelvin (by adding or subtracting the value of absolute zero in Celsius).

Yet, it's not SI, because it's for humans. The same could be said for using km/h. The rest of the world measured speed in km/h which is derived from m/s (multiplying by a constant).

They're presenting units that people are most familiar with, that most people see and experience, modulate with their foot, every day of their lives. The presentation is for humans, not calculators. The best way to make people interested is to make things relatable, and let the interested people do the trivial math they're so familiar with. It's good PR, and an example of why engineers shouldn't be involved with PR.
