"There are two types of countries in the world: Those that use the metric system and those that have been to the Moon.(1)"
(1)I purposely leave Liberia out of it. Unfortunately, I think it still might be a few years before the LSA gets to the moon.
"There are two types of countries in the world; those who have some sort of national paid law for new parent(s), and those that have been to the Moon (1)"

The use of two different systems was the root cause
in the loss of the $125 million Mars Climate Orbiter.
NASA specified metric units in the contract. NASA and
other organizations worked in metric units, but one
subcontractor, Lockheed Martin, provided thruster
performance data to the team in pound force seconds
instead of newton seconds. The spacecraft was intended
to orbit Mars at about 150 kilometers altitude, but
the incorrect data meant that it probably descended
instead to about 57 kilometers, burning up in the thin
Martian atmosphere.https://en.wikipedia.org/wiki/Myanmar_units_of_measurement#A...
