We have to learn both in the US. I was in 6th grade in 1972
and we were using it then. I remain unimpressed. The
acrobatics that are done to convince people that metric
is easier are silly. First they have you convert meters
to centimeters (a calculation nobody ever does) and
then they have you add 6 tons 50 pounds 9 ounces to
2 tons 742 pounds 13 ounces (also a calculation nobody
does.)

It is a fact that in almost all real calculations in
English units, one unit is chosen and it is decimated.
The only exception I can think of off the top of my
head is that carpenters like their denominators to be
powers of 2. Otherwise, most people would calculate
using number like 15.53 feet. Every bit as easy as
the same calculation in the metric system.

<grin> Then you don't plan to write a cookbook which
will reproduce the same taste and nutrition. Cooking
and baking are acts of chemistry. Canning is also chemistry
plus a dash of physics and a large dose of microbiology.
Personally, I'd rather be in a chem lab than the kitchen.

I grew up in the US and cannot think in metric terms so I
always have to do a conversion to make guesstimates.
For some strange reason, kilometers seem to take "longer"
to drive than miles when I drove from Buffalo to Port
Huron, Michigan. :-)

What system do geologists use? There was an argument in
sci.physics about 12 years ago w.r.t. which system was
preferred in doing physics work.

That's happening already. It won't help. The key is for people
to begin to exercise self-responsibility. I don't think will
happen.

And Arpanet won. What is your point?

Actually that better way wasn't much of an improvement until GUIs became
commonplace.

Might have been clunky but ftp is not slow.

You are aware, are you not that Netscape is based on Mosaic? And that
Mosaic is not text-based?

Actually when you use TeX you are formatting in TeX--there are translators
that let TeX documents be printed on PostScript printers but they aren't any
different from any other printer driver.

Actually Word predates the Web by almost a decade, and is roughly
contemporary with TeX. TeX was a more capable system by far but also more
cumbersome.
