I don’t get US spelling of “meter” for the metric system they don’t even use. My car dashboard is two meters wide. Speedometer and tachometer. It’s probably about half a metre wide.
I dunno what a kilometer would be. A device that can measure anything in thousands of something; weight, volume, speed, etc.
“The scale says you weigh 0.07 metric tonnes.”
“Oh my god, I’m so fat.”
“No, that’s only 70kg, it’s this stupid kilometer. Makes everything seem bigger than it is.”
