On: Let the Type System do the Work

miles = constant * km though, you simply scale one to get the other.

f = m*c + b, which is both a scale and a transform.

But as stated above, Dimensional already does Celsius to Kelvin and vice-versa. Which is indeed of the form you just stated:

f = m*c + b

where m is simply equal to 1. Why wouldn't Fahrenheit conversion be the same thing, just with different constants?

Me no reed gud :-\

Yeah, you're correct.
