The metric system doesn't have fractions but they do have:
and on and on and on.....
Not saying it's better..... it is what it is.....
There was a thread not long ago where someone was asking how to convert 4/32 or some such into decimal so he could then convert to metric. Hence the revelation...
I can work comfortably in either system, and know that neither is superior to the other. If you're participating in an International forum it's handy to be able to at least convert into whatever you're conversant with.
In 1971 or 51 years ago I had a math teacher who swore that we would soon be required to know the metric system as the US change was soon approaching. To make his point he wielded a meter stick much like Patton and his riding crop. He used it as a pointer and to swat any inattentive or unruly student across the bicep leaving a bright red swatch the width of the stick.
Seems like other than a few ammunition calibers and modern vehicle engine designations (tire sizes are a combination of both systems) we are still not there.
We had a meter stick at home when I was growing up, one of those big, thick things physicists use in the lab. There was a Cosby bit about his wife wielding a yardstick as if it was a Samuri sword. That was nothing compared to what my mom could do with that meter stick.
