  • Hi and welcome to LARN!

  • Now as many of you may know, when America gained their independence, the British left

  • something else behind besides their language.

  • Yes, you've guessed right!

  • I'm talking about their measurement system.

  • Or, at least, some of it.

  • Although the British later partially converted to the metric system, the U.S. decided that

  • they didn't mind being the black sheep after all.

  • [Sheep bleats] And they decided to stick with their own measurement system, also known as

  • U.S. customary measurement system, also known as This-is-how-we-measure-stuff-deal-with-it

  • system.

  • Now, to tell you the truth, the U.S. had to give in a little bit at some point.

  • In fact, in 1975, in order to make things easier in a more globalized economy, the U.S.

  • decided to adopt the metric system in at least a few fields, like medicine

  • and the military.

  • Sir, the target is 4 meters away, no wait.

  • 40 meters away.

  • No, wait.

  • 400 meters away.

  • I don't know...

  • How many meters in a yard?

  • Now, although the origin of the imperial system dates all the way back to the Romans, I can't

  • help but imagine that when they decided to create it, things sort of went like this.

  • Okay, John.

  • You heard 'em.

  • Create a new measurement system and have a little bit of fun with it.

  • So...

  • Let's say an inch is about this much.

  • Hmm.

  • No.

  • Let's say it's this much.

  • Yeah, that looks good.

  • An inch is this much.

  • Now the foot.

  • Everybody will probably expect me to pick a number that's easy and predictable.

  • Something like, I don't know, 10?

  • [Chuckles] But no, no, no, John.

  • This is your moment to shine.

  • This is your chance to make history.

  • You need to wow them.

  • Let's do...

  • 12! 12 inches in a foot!

  • Now for the yard...

  • What's my favorite day of the month?

  • Of course!

  • My birthday!

  • October 3rd!

  • So...

  • 3!

  • In a yard, there are 3 feet.

  • And lastly, a mile.

  • [Stomach grumbles]

  • Oh gosh, I'm hungry.

  • I'd better wrap it up quickly.

  • Okay, first four numbers I punch in this anachronistic calculator on my desk will tell me how long

  • a mile is going to be.

  • Okay, then.

  • 1- 7 - 6 - 0.

  • Perfect.

  • So, in a mile, there are 1760 yards.There, all done.

  • Bravo, John.

  • Well, anyway, now if you're not familiar with this system you might need some help trying

  • to figure out what each unit corresponds to.

  • So here are a few tips.

  • If you want to know how long an inch is, just grab a fork.

  • And measure it this way.

  • Now, if you want to know how long a foot is, then just grab a regular notebook.

  • And measure it this way.

  • And now, if you want to know how long a yard is...

  • Well, then just grab a guitar!

  • No, no, no, no!

  • Don't throw it!

  • Now, this is a little longer than a yard but it does give you a pretty good idea of how

  • long a yard is.

  • And what about a mile?

  • Well, that's easy!

  • Just go to Paris!

  • Since you're already there, well...

  • Make sure you make a stop to check out the Mona Lisa.

  • Maybe try some of the local food.

  • And then head straight to the Eiffel Tower.

  • And imagine stacking about about five of those and you got yourself a mile!

  • Well, I hope I've helped you figuring out a little bit how the U.S. measurement system

  • works.

  • So, go ahead!

  • Have fun and measure stuff now 'cause you can do it!

  • Thanks for watching!

  • Bye!

  • Hi!

  • And welcome to LARN!

  • Hi!

  • Hi!

  • No, I was supposed to do it before.

  • I have to do it again.

  • So let's take the ---.

  • Try to throw it a little more straight.

  • You might need some help in figuring out ---. Figuring out which ----.
