I am a scientist/engineer and professionally I use SI units exclusively.
After all, SI is the universal scientific/engineering language.

However, in my daily life I prefer the traditional units. I want
to purchase gasoline in gallons and not liters. I want to buy
potatoes by the pound and not kilograms. I want to drive my car
in miles-per-hour and not km-per-hour. I can easily live in both
unit worlds.

Consequently, I am opposed to any kind of legal imposition of the metric
system (SI) to all human affairs.

Keep SI in the laboratory. Keep tradition in daily life.

Now I shall quaff a cup (not 200ml) of cheap wine, drawn from
a hogshead keg.

Ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha!

I favor going all Metric.

Amendment XIV
Section 1.

[...] No state shall make or enforce any law which shall
abridge the privileges or immunities of citizens of the
United States; nor shall any state deprive any person of
life, liberty, or property, without due process of law;
nor deny to any person within its jurisdiction the equal
protection of the laws.

Dobbs rewrites this, it is invalid precedent. States are
liable for denying needed abortions, e.g. TX.

It started that way, but since about 1976 or so the official definition
has been 1852 metres exactly.

A few countries (China, Russia?) use SI units in their aviation. When you
pass through their airspace, you have to do as they do.
