00:01 Welcome, ladies and gentlemen, to the world pressure tournament, brought to you by number four from chapter 12.

00:08 I'm your host, jeremy.

00:11 Today, we've whittled our competition down to just four contestants.

00:15 363 millimeters of mercury, 600, 363, excuse me, kilopascals, 0 .256 atm, and 0 .523 bars.

00:27 Let's go to our co -host bob, see what he has to think.

00:32 Our contestants today, they're really going to be feeling the pressure.

00:39 Bob, you're fired.

00:41 Today we'll be ranking these contestants in order from least pressure to greatest pressure.

00:47 Let's go down to our head judge matt, or he'll explain the ranking process.

00:52 Thanks, jeremy.

00:54 So we're going to be starting out just addressing the beginners in the room.

00:58 If you've never converted units before, there's a very basic setup.

01:03 The gold standard is the atmosphere.

01:05 And i have listed on your screen the unit conversions, the equivalencies of atms to millimeters of mercury, kill pascales, and bars.

01:15 And if i want to take our first contestant, 363 millimeters of mercury, and i want to be really, really certain how it compares to our second contestant here, our 0 .256 atmospheres.

01:28 I would do a simple unit conversion where i take our contestant and i multiply that by one atmosphere over 760 millimeters of mercury.

01:46 And i could do this for any of our contestants here.

01:48 I could do it for our kilopascals and our bars where i would put that conversion factor on the bottom.

01:55 That way our units millimeter of mercury, millimeters of mercury cancel, and we have our answer in atmospheres.

02:02 And if you really, really got a close contest, you need to go to the calculator finish, you'd be able to plug that in and find that 363 millimeters of mercury is about 0 .478 atmospheres.

02:19 So right away, we have a stratification in the contest and our contestants.

02:23 We can see that we've got a poor performance from 0 .256 atm.

02:28 So far, that's our lowest pressure and our 363 millimeters of mercury, that's about doubling our previous contestants, a little bit less than half of an atm.

02:47 Let's go ahead and look at our next contestant, 363 kilopascals.

02:51 Now, when you've been doing this for as long as i have, you don't need to do all these calculations...
