the usa tried converting to metric long ago and it did not work.

there's also nothing wrong with imperial measurements.

think about which country put people on the moon, put spacecraft on mars, did a flyby of pluto and landed a spacecraft on an asteroid.

hint: it was a country that uses imperial measurements.

Then.

The USA has numerous specifications for mechanical components, specified in metric units. This includes nuts, bolts. bearings, structural steel, sheet metal. All of these specifications are required because metric components are in extensive use.

some are, and plenty are imperial. my cars have a mix of both.

creeping is not the same as completely changing.

american cars have had metric parts for *years* and are still not yet 100% metric.

meanwhile, the number on the sign posts are miles or mph, motor vehicle regulations discuss feet or miles, along with plenty of other stuff.

it ain't changing any time soon.

Eric Stevens
Many of the components in your computer use metric dimensions etc.

nospam
like a 2.5" ssd or 3.5" hard drive? or a 12" or 15" display? or a 3 pound weight?

both numbers are listed.

meanwhile the drives are marketed as 2.5" or 3.5".

Eric Stevens
Whether you like it or not, the metric system is creeping up on you.

nospam
it isn't.

some stuff might be metric, but definitely not all.

Eric Stevens
Not yet.

nospam
not any time soon.
