 I'm doing I make videos I teach I teach math So this is this is just doing mathematics. I'm How to do unit conversions? Like have you guys did you guys do math? Are you taking math? Have you guys done any converting units? Like do you guys do stuff like going to the store pay a dollar by two candy? Yeah, that's unit conversion because you're giving you're giving somebody a dollar And they're giving you two pieces of candy Right, so that's that's all I'm doing. I'm sort of gonna teach teach teaching how you do it generically like for color squares and triangles and then you can apply that wherever you go like for example if you go to a store if You have if you have two dollars, right? You could buy seven Orange boxes, right? So if you have two green boxes, it could be your two dollars You buy seven Something chocolate bars if you want. Yeah, and I put it on you, too Hi, this is chichou again, and if you've been following the language of mathematics, you would have recognized this wall Someone's already been here for a happy face on there we've used this wall a few times over the last few years in the previous four series that we've done and It served us pretty well, and we're here to you know use it again And we're gonna do sort of lay out the work This is concept what we're about to do For the first few videos in the units and ratios section, which is basically to learn how to do unit conversions How to move from one system to another? So the way you should think about a system is basically us human beings Grouping things together things that have similar behaviors things that have similar properties, right? Or things that have similar ideas similar thought patterns, you know if you're preparing food We ended up calling that cooking right if you're making pastries We ended up calling that baking right if you're studying the motion of objects We've ended up calling that kinematics, which is a branch of physics What we're gonna do is take a look at some of these systems Just list some of these systems and take a look at some of the unist that exists within the systems, okay? You know science engineering Technology medicine food fitness or fashion music gambling economics or politics and some of these some of these systems some of these disciplines Overlapped with each other a lot of these things overlap with each other Some of them have units that only exists within themselves a lot of them have units that exist Beyond themselves, right? They cross over between all the different Different disciplines that exist here Sciences again, it's a large umbrella. It has multiple branches going going off multiple systems multiple disciplines going off There's get in sciences. There's there's physics. There's chemistry. There's biology. There's earth sciences and meteorology Astronomy whatever you want, right? And each one of those has a sort of discipline within itself physics has kinematics physics has Electromagnetics, right? You can just study just continue to branch things off and go deeper and deeper into a system And as soon as you group things together as soon as you branch off and find it Find a whole bunch of other things that interact in a similar way Then you might create specific units that exist within that system only so let's list some of these units that we may encounter and Just just you know, so so that we're familiar with them. Okay Now there's seven base units that cross over a lot of these different disciplines these different systems And for those we've come up with the international system of units Which is recognized almost everywhere except three countries, which is the United States Liberia and Burma and those are the seven base units that have written down here, which is meters kilograms seconds and peers Calvin moles and Caldera, I've never I've never used it myself. It's and they represent each one meters is, you know, length We need to find out how how long things are right how, you know What what their dimensions are right and that's internationally we use meters There's also the imperial system which uses feats and inches and And miles right there's kilograms for weight the other system is Is pals which is we'll use beyond you know outside of the United States Liberia and Burma in Canada When you start talking with people very few people give you you know If you ask them how much they weigh very few people will tell you how much they weigh in kilograms They use pounds right so these international systems that have been developed They're not necessarily used in everyday talk and they're not necessarily used in every calculation. There's Seconds seconds time. It's pretty internationals Seconds and you know, I don't know any any country in the world that doesn't use seconds, right? There's amperes research at your current and current again as far as I know amperes is used internationally this Calvin, which is Unit that we use for temperature in the sciences in calculations because it's convenient to use Calvin It works with a lot of different formulas and a lot of different properties of different materials But in every day speak and I don't know any place in the world if you went up to someone and said hey What's the temperature outside? They would give you the temperature in Calvin You're either talking about degrees or degrees Celsius or degrees Fahrenheit Fahrenheit and then there is a Moles which is the amount of a substance and that again is never used in everyday life because moles is a huge number which is used in chemistry for finding out talking about molecules, right and You know if you had a mole of people that would be probably take over the world or something like this, right? So moles is very specific to certain disciplines here certain Certain systems that exist and the other one CDS caldera. It's it's luminosity. I don't I've never used it myself I might have used it when I did my studies in sciences, but I never used it myself in everyday life now in these SI units the first three those basically Encompass every system that we're talking about right if you're if you're running you talk about how far you've ran if you're if you're Make you know doing reps. You're talking about how much weight you're lifting, right? If you're cooking something you're looking at your clock and you're figuring out how long you've had your Pastry your pastry in the oven or or whatever you have on the stove, right? If you're talking about economics There's time involved in economics. There's distance involved in economics There's weight involved in economics, right? If you're going to be selling something Taking something from one location transporting to the other you need to take into consideration distance, right? you need to take into consideration the weight of the The things that you're transporting from one place to another you need to figure out how long it's going to take you To take something from one place to another, right? You also need to you know, if it has to be refrigerated you have to figure out how to refrigerate it now when you're doing that You're not going to start using Kelvin. You're going to start using degrees or fair and you're going to start using Celsius or Fahrenheit, right? You're going to have to figure out How much Quantity of a material you have but you're not going to measure them in moles You're going to measure them in whatever system that you're using to do your business, right? To to conduct your politics, you know, may it be dozens may it be crates, okay? So these seven SI units they're used internationally for calculations in the sciences specifically Now from these SI based units you can drive a whole bunch of other Unists which are basically called SI drive units, right? And that's unlimited and they come into a lot of different disciplines May it be music, may it be medicine, may it be economic, fitness, may it be in cooking, in baking, whatever it is that You're studying There's going to be some form of units that you're going to be using which are SI units or derived from the SI units Okay, so some of the derived based units here is you know, there's a whole list of them It could be Hertz which is one over seconds. You could have radians. You could have Newtons, Pascals, Joules, Watts Coulombs, if you're talking about volume of something you talk about leaders if you want if you're getting into Electricity, you're going to talk about volts if you're getting into magnetic flux them if you're studying magnetism You're going to get into Tesla. Okay, you're going to encounter Tesla Which is the magnetic flux of something and if I can recommend something to you if you're gonna if you want to read about You know some of the accomplishments of some one of the greatest scientists that our species has produced look into Nikola Tesla because What what he was able to do is the the foundation of our society Which is you know bringing like you you know introducing a system We were able to use electricity the way we are able to use it right now some of the ideas that he came up with and Again, if you want to study someone's Someone's work life work and how that has influenced our society Definitely look into Tesla and some of the stuff that he created and some of the ideas that he had You won't be disappointed. Okay Now for us to be able to figure out how to do unit conversion We're not going to study a specific system because as I mentioned before mathematics It's just a language and how you use the language is very personal So if we start delving into a certain discipline to learn how to do you do unit conversions We're going to alienate somebody right because I may like something that you may not like so what we're going to do We're going to learn how to use unit conversion on a generic system We're going to come up with your own little scale system and we're going to figure out how to just apply mathematics to switch from one system to another and The way we learn how to do this is going to work with whatever system that we're going to study because We're not really concerned about right now Delving into a system and learning how the system works. That's going to come into Play we'll start doing math in real life and start applying some of the mathematics What tools that we have in real life may be for gaming and gambling Economics politics whatever it is food and fitness may be in sciences, right? So what we're going to do right now is Set up a sort of our own scale system We're going to use this for a few videos just to learn how to do Conversions from one unit to another and that's where ratios is going to kick in so I'm just going to go here Lay down the system and we'll take a look at it and discuss it very briefly but keep this in mind what we're about to do and definitely keep this in mind because This is what units are units are sort of a convention that we've come up with to explain certain properties of Things in certain disciplines right in certain systems that we're either functioning in or studying So this is the scale system that we're going to use to learn how to do unit conversions from one system to another From one unit scale to another Okay, and it's basically you know a generic system that we've come up with the if you want call it the The realm of colored squares and triangles, right all it means is Over here if you have two boxes two green boxes equals Seven orange boxes. So if you had two green boxes the boxes would be your units And the green boxes would be your units over here and the orange boxes would be your units over there, right? So if you have four green boxes, then you should get back 14 orange boxes, right and that's all it is and it's a relationship between Colored boxes to each other and colored boxes to color triangles and color triangles to color triangles, right? So it's basically a pointing device telling you what is equivalent to what? Okay, and that's all we're doing right? We're using ratios and what we've learned about the equal sign to be able to convert from one unit to another That's it for now This is going to be what the units and ratio section is going to be about and you know We're going to build on this and grow it to a level to a place where we can actually go into certain disciplines Go into certain realms and start working with them and understanding them based on the units that we're being presented I'll see you guys in the next video. Bye for now
