What do you do your metric systems?

Globel satandards of mesurements are the metric system.
When I go to shopping and ask something about what I want to buy, if the people working there
from abroad, it is easier to discuss about the size, weight and so on.
Because they know the metric also.

One of the reasons that American Auto Industry is losing their share in the world is that they do not use the metric system.
Except American and British, rest of the world mesures by the metric systems.
No yard, inch and pound.

I know my weight by pounds because I do boxing. 138pounds is my weight.
But when I am asked how many inchs your height, it is confused.
I always answer differently.

Ironically, the calibers of the guns is the first thing that Americans is adapting the metrics.
9mm, 5.62mm and 11mm are European metric caliber which Americans have all.

If Americans and British are using yard and pound system, they will reach to some ceilling
someday.

The metric system is one of the rare victories of French.
