Why do you guys still cling to your variant of the imperial system when the metric system is easier to use?
Because it isn't, for several reasons, the most salient of which is that we all know the Imperial system and it's hard to learn a new one.
This is like saying "Why do you guys still cling to the English language when Spanish is so much easier?"
While it's true that Spanish is probably an easier language to learn, objectively speaking, if you start with zero prior knowledge, most Americans already do speak English and don't speak Spanish, so it would not be "easier" for all of us to learn Spanish than to continue speaking English.
1) you can learn metric in an hour
That depends what you mean by "learn." I highly doubt you can internalize the metric system to the degree most of us have done with Imperial in an hour. Well, maybe you can. I doubt I can. I know beyond doubt that most Americans could not.
2) if you are doing calculations involving measurements then metric is easier to use even if you don't 'know it'
True -- but most people don't have to do complex calculations involving measurements on a regular basis. It's far more common for them to need to eyeball things and get them in the ballpark, and/or have an intuitive idea of the meaning of the measurements -- and for most Americans that's far easier in the Imperial system.
3) refusing to force kids to grow up using metric just because we adults are intellectually lazy doesn't seem like a good idea
Maybe it is and maybe it isn't. I was asked why we do as we do and I answered.
However, since you raise the point, see my argument about adopting Spanish. Also, Imperial units are part of our patrimony.
4) mm/cm pwn inches
Completely subjective. I disagree. Apparently whoever is in charge of American measurements does too.
5) scientists, medicals, etc. already us metric, with glee
And they are welcome to it. It makes sense for them. For Joe the Plumber not so much.
I despise metric baking. 1 cup is much easier than 250ml and 1/2 is easier than 125ml
Same with tea/table spoons
weight metric though? I do prefer grammes to lb/oz though with a scale it's easy to flip
F Gives you precision, and for weather wise I don't like the idea of negative degrees at all. SO my personal preference if we would switch would be to K, but that'll never(and shouldn't) happen
distance: take it or leave it I can do either
My height i do know and I'm okay with in either system
Weight though, saying I'm 107kg makes me feel a lot better than 230some haha
Also, i prefer using fractions and things such as 12 in=ft and 3ft=1yard than forcing decimilization
