Rest of the world: meters, cm, mm

The US: gerbil teeth, lark tongues in aspic, toenail clippings on fire

I especially love it when they use the weight of an airplane as a comparison. “It’s as heavy as a Boeing 747”. Even if someone had an intuition about the weight of something that large, they would probably be wrong because aircraft are relatively light for their size, it helps when you need to fly. Everything in a plane is made to be as light as possible, so nothing on board of it would weigh as much as the non-aircraft equivalent you’d be familiar with.

Excuse me but the correct SI units for length and area are double-decker buses and Waleses respectively ☺️
