It would be better if we did, but there's a strong resistance to change
Because were slow haha!
We do. It depends on what we are doing. Sometimes it is easier for me to just use the metric system because everyone else in the field is doing the same.
Because we are resistant to change, we pretty much don't like any idea that didn't originate here. Just look at universal health care to see what I am talking about.
We like our system. Silly. Besides, we have metric..if we turn our rulers and things upside down.
I was the kid in the 70s all set to make the conversion, but, well, you know how it worked out.
