no that's not the point. if you let rust automagically decide when and where to apply conversions you could easily wind up in a situation where you have more operations than you need, which increases numerical error, and also be a bitch to uncover or refactor to minimize conversions.
That’s a good starting point. The temperature delta issue remains: adding and subtracting temperatures should create a different unit. Thankfully there aren’t a lot of non-linear units.
thats why i put the word "you" in there. rust will do whatever automagic conversions you specify in the impls. Perhaps i should have used the verb "make" instead of "let". if you make rust automagically convert.
