Ah, late 70s is what I’m finding is when they converted to metric. Guessing that happened right after Ford announced the Metric Conversion Act at the end of 75’

Favorite part about that:
“The Metric Board was abolished in 1982 by President Ronald Reagan”
Although Americans used to use cubic inches for engines…
Huh, never heard that before. Any examples? Like Chrysler, Ford, GM, used liters. Must be before my time.
America used cubic inches for most of the 20th century. The chevy big block engine line was pretty popular, check out the different sizes it was made in: https://en.m.wikipedia.org/wiki/Chevrolet_big-block_engine

That’s my least favorite part. I hate that the US still uses and teaches its archaic and just plain stupid customary units.
Yeah I was being sarcastic about that lol
