I believe there was a half-hearted attempt to go metric in the '70's.
Other than for scientific purposes, I don't ever expect the United
States to officially adopt the metric system, although it would
definitely benefit from doing so.

About the only effect of the 1970s effort is the two-liter soda bottle.

Also the displacement of automobile engines changed from cubic inches to
liters. KM

And most speedometers seem to have metric displayed along with miles,
though not as prominently.
