...and the SAE system like me (older American here) then you would be able to provide the answers that confuse your audience the most when they ask about volumes, velocities, dimensions, etc. and you would have as much fun in life as I have had. Your metric system is for people who need to have things simplified in order for them to be understandable and relatable. It's about as dumbed down as you can make something. Lowest common denominator type stuff. Americans have always thrived on challenge and that is why we stupidly cling to the complexity of the SAE system of units. It fits so we sits.

They do use the metric system at NASA maybe that’s why they haven’t been back to the moon.

Not homogenous though.

that's not a sandwich, it's a pizza
