This was all the rage, about 35 years ago. The media and government kept saying America must change to use the same units as the rest of the world. We must change!!!
But we didn’t change for the most part. We have liter gas and liter sodas, but not much else on a regular basis.
Metric? Really? How very ‘1983’ of you, Lincoln.

We have liter gas and liter sodas, but not much else on a regular basis.

Grams and milligrams are actually kind of useful for nutirional information. Better than some of our small measurements (e.g. grains).

Interestingly, gunpowder is still measurted everywhere with the old school measurements as far as I know.

Other than the U.S., what other country still uses the old English System of Units?

While the rest of the world is pretty much standardized on the metric system of measurements, when it comes to mandatory use the big holdouts are the United States and Great Britain, Liberia and Burma.

Jimmy Carter tried to do this. America rose up and responded with a resounding “F**k, No!”. Just like the 55MPH speed limit.

Of course that was in the 70’s. Today people are practically sedated sheep by comparison.

Canada went ahead with metric, and even today I doubt to many Canadians my age or older really have any concept of how long a kilometer is.

So, the international standard for the thread that holds a propellor on an outboard motor - is an inch standard thread! 7/8-18, IIRC.

Lots of metric fasteners nowadays, and I think things generally moving that way. I don;t see any value in coverting our common temperature and distance to metric, but no big downside either.
