Every time the US citizens dare to complain about their weather, people who live outside the states usually mock them for the use of Fahrenheit, as pretty much no one knows temperature they’re exactly describing. But the temperature scale is not the only measurement that has people around the globe confused. Why? Because the USA uses the imperial system while most of the world uses the metric system.

As a system of units, the imperial system was first defined in the British Weights and Measures Act of 1824. It was later reduced and refined, however, most of the countries that used it (the British Empire and colonies) have since moved to the metric system. Well, not our dear ole states. They simply switched some things up, put a label “United States customary units” on it and went on their merry way. Still, doesn’t mean it’s not going to confuse the rest of the world.

And it surely confused one Twitter user, Innes McKendrick, who went on quite a rant after taking a closer look at some of the measurements. “The reason I made the horrific discovery was a paragraph in Mike Clelland’s Ultralight Backpackin’ Tips book: “The math here is all done in ounces. With 16 ounces to a pound, conversion gets a little tricky otherwise, unlike that ingenious metric system”. Obviously I was floored. SIXTEEN. Wow. I guess I figured it would be about 12, but never bothered to check given that I’m more than adequately served by the universally superior metric system” McKendrick told Bored Panda. He also went on to explain that he’d not be coming back to the topic of imperial system as he feels he does not possess the “mental fortitude to take a second look”. Scroll down below to read what he had to say, and don’t forget to tells us what you think in the comments!
