Imperial adds unnecessary conversions. Multiplying and dividing should be simple, but every such calculation with imperial requires mixed fractions --> conversion.
Also, you switched meanings of "conversion" in your second sentence. If you can't make a point, just say so; don't play word games.
my point is that conversion is necessary no matter what; it's universal. Hence the metaphor.
what you call "unnecessary conversions" is only true in limited circumstance. Those "unnecessary conversions" can be a livesaver depending on what you're working with. Also, much of the metric scale is linear despite almost nothing in nature scaling linearly. Some of phelps's comments give good examples.
What is 5’ 3 2/32” / 2? Now, what is 5254mm / 2?
Yeah the "evidence" in support of these stupid claims only goes one way. "Want to divide 3 feet by TWELVE?!? E Z P Z with our newfangled imperial system!"
reductive. You're giving a limited scenario, like I already said you'd done.
how about that linear scale issue?
unnecessary conversions can be a livesaver
So your premise is that being able to convert quickly in some situations is a matter of life and death, and you would rather do MORE math than LESS? What in the world are you talking about?
much of the metric scale
How much?
... is linear
Really? Why do they name every 3 digits then? That's not linear.
almost nothing in nature [scales] linearly
What are some things in nature that scale, and how do they scale? You sure seem to know a lot that isn't so, but maybe I'm in the wrong.
