Okay, in this slide here are in this section, I should say, we're going to talk about length units in the metric system. Alright, the standard unit of length in the metric system is the meter. I. And just to give you an idea of how long that is, or give you a sense of that sense of the distance, one meter is 39.37 inches long, so it's about three plus inches longer than a yard. All right. Okay, so When I talk about I'm saying one kilometer, all right?

A kilometer is 1000 meters. All right, so that's the length of one kilometer. So if I took 1000 meters and put them into end, that's how long that would be. A hecto meter was saying 10 to two meters, but one hecto meter is 100 meters long. I deca meter is 10 meters long. All right.

So, from here to here, they're all numbers or we have lengths that are a meter or group All right, from here to here, you'll notice that my exponents are negative. So these are less than a meter. Okay? So for instance, what I mean by this is a centimeter, okay? Is 100 of a meter, or meaning. If I took my meter and divided that meter up into 100 equal slices, that would be a centimeter, a millimeter, I take that same meter and I divide it up into 1000 equal sections, and one of those sections is a millimeter.

And then I have a micro meter, which is the last one here. All right, and I take that meter and I divide that meter up into To 1 million sections. So one of those sections is a micro meter. Okay? Just to give you an idea. All right.

So getting back to the English system of the length, which is what the US United States is on, one mile is 1.61 kilometers. If I take an inch, okay, that inch would have 2.54 centimeters and remember what a centimeter is we took it over here. All right? I'll foot is point three meters. And era is point nine meters. All right.

So that'll give you an idea of, of the length units in the metric system. And the length units in the English system, which is what we are here in the US. Alright, so that'll give you an idea. So let's clean off the slide. And let's, let's go to the next. The next slide.

Okay in this in this slide here, or, I mean, I thought we want usually we want to convert from from the metric system to the English system, which is the US. And what I say here is, okay, three meters, is how many inches? Well, if you go over here, you'll see that 39 dot three seven inches equals one meter. So if I multiply that is my answer. All right. 118 dot 11 inches.

And if I want to know how, you know I got 2.5 Miles, I want to know what what that is in kilometers. Well, there's my my multiplication right there because one mile equals 1.61 kilometers. So all I do is multiply 2.5 times 1.61. And there's my answer. Okay? So that's, that's not a difficult thing.

However, let's, let's close this. We've got something that's really wonderful. I'm not sure if you guys know this, and there's, there's my, my standard calculator. Let me get there we go. All right, let me Okay, there we go. We just adjusted the screen.

And if you come over here, notice again, I'm using the Software calculated that comes with the Windows operating system. I go to converter. And what do I want to convert? Alright, notice I've got centimeters inches. So let's find, let's find meters here. I want to go to meters, two inches.

So I just plug in three. And there we go. There's my answer. All right. All right, I want to go from let's do, let's clear it. And let's do I want to do 2.5 miles.

So I go two miles, right there. And I want to go two kilometers right here and so all I do is type in to point five. And look at they're actually we're a little bit off a rounded up here, but we're close. Okay, we're close right there. All right. So that's it.

So, I mean, it's built in the calculator for something like this, if you can understand the mathematics, fine, but use the calculator. Okay if you need to. All right. All right, let's stop here and go to the next slide. Okay, here's a little exercise again, use the calculator. Like I explained to you if you don't have windows.

I'm sure if you go online to Bing or Google and say, metric system converter length units, something will pop up. But that one was with the Windows operating system. And we want to go from 12 inches to centimeters. 55 miles. kilometers, one meter to how many inches? 10 kilometers to miles.

Three miles equals how many kilometers? 24 inches equal? How many centimeters? three feet is how many meter and three yards is how many meters? Okay, answers on the next one. If you get the right calculated this shouldn't take you that long.

See in the next slide where the answers are. Okay, here are the answers for you. Take a look at them. If you didn't get them, go back and make sure you're entered the the right way okay. Or maybe you hit a wrong key. Some of them I rounded up or rounded down.

Okay, so if you're like off a digit, okay, we rounded differently that's okay. But for the most part, the difference First three digits should should match. Okay, so enough on this again, if you have a problem, go through the previous slide. Look at it again. It shouldn't be that difficult. All right, seeing the next slide.

Okay, here are the answers here. I'm not gonna say every answer you can see them The only thing I'm going to say is you the decimal decimal point, or the the answer to the right of the decimal point may vary a little bit. So be aware of that because the way we round off, but those should be pretty much it. I've checked them. So if there's any issue or you think they're not right, send me an email, give me a call. Alrighty, um, that said for weight units.

So again, use the converter with the operating system and we're good. Okay, next section is temperature. All right, we're talking about temperature units now. And where here's a formula right here. To convert from Celsius to Fahrenheit, we use Fahrenheit in the United States, and I believe Europe uses the Celsius model. And then this equation here will convert from Fahrenheit to Celsius.

So that's pretty much it. So I give you a couple examples here. We want to go from 212 Fahrenheit to Celsius. So we know that 212 degrees F is boiling in the US, so it's the temperature that water boils at. So here's the here's my equation I'm going to use I'm just going to plug in, so my temperature in Fahrenheit is 212 degrees. I'm going to actually subtract 32 degrees, then I'm going to multiply five ninths by 180.

Because one 212 minus 32 equals 180. So five ninths times one 880 equals 900 over nine. And if I divide 900 by nine, that equals 100. So the answer is 212 degrees F equals 100 degrees C. All right? So the boiling point in Fahrenheit is 212 degrees. And the boiling point of water using Celsius is 100.

That's it. All right. Let's clear the slide and do one more Okay, on this slide here, we want to go from zero degrees C to Fahrenheit. And so we use this equation here. So I just plug in my numbers, we want to go from zero to what, what is the equivalent of 00 degrees C to Fahrenheit. So again, we use that one, so nine nine fifths times zero, because we got zero degrees C plus 32.

Well, zero times any number is zero. And we're going to add 32 to it. So my answer is 32 degrees F. And that's it. 32 degrees F Fahrenheit is the temperature at which water freezes at and zero degrees Celsius is the temperature in Celsius that water freezes at, so we're good. I know Okay, let's go on to the next slide. All right, well, here's an exercise that you guys can do.

But then again, we can bring down our calculator and we can convert these also. Let me let me do that. So what I'm going to do is bring down my calculator. And let me fix the slide here. And here's my calculator. So again, I want to do what I want to go to converter.

And what do I want to convert about temperature? All right. And I'm going to do one I'm going to say, let's do 100 degrees Celsius, as we did before, one and that's 212. degrees Fahrenheit, like we saw in the previous slide. So let's clear this one. So basically what I'd like you to do, I've given you four examples here. Try it with the calculator using the conversion, as you can see here, and then try to plug it into the formula and in check yourself.

All right, that's a good exercise. It may take you a minute, but you know, it's good to know, it really is good to know. So with that, when you finish, guess what, when you go to the next slide, you'll see the answers. See over there. Okay, yeah, the answers. I see if you get them.

I didn't really do them out. I just plugged them into the converter on the calculator. But they're there. I mean, they should be good. So this actually concludes this section on metric system and on temperature. You It's a next section is going to be on algebra.

And we'll see you over there. And again, the next slide will have a phone number. If you have a problem call me once again, I do not return international calls. However, you if you send me an email, we'll set something up. I'm here. I can't say that I'm here all the time.

But if you leave a number and you're within the US continental US, I will return the phone call. Just leave a good time to call you. I may not be able to do exactly at that time, but I will return your phone call. With that said I will see you in the next section.
