### Transcription: Units of Measure

Welcome back to Educator.com; this lesson is on units of measurement.0000

We are going to look at the different types of measurement, starting with length.0005

To see how long something is, we have different measurements.0013

1 foot we know is 12 inches; 1 yard is equal to 3 feet.0021

1 mile is equal to 5280 feet.0029

Using this, we can convert from foot to inches, yards to inches to feet, and so on.0034

Also for length, we have meters; 1 meter is equal to 100 centimeters.0043

It is also equal to 1000 millimeters; 1000 meters is equal to 1 kilometer.0054

The key here in converting is... you should know all of these.0061

But it is also to determine which measurements are larger, which ones are smaller than the others.0069

Right here, centi means 100; but it means small 100.0081

That means to make up 1 meter, it takes 100 centimeters.0088

If I said that this is 1 meter, then it takes a lot of centimeters, 100 centimeters, to make up 1 meter.0097

We know that the meter is bigger than the centimeter; centi means 100.0117

Anytime you have anything with centi, it just means 100, but in a small way.0122

They are very small.0127

Same thing, 1 meter, it also takes 1000 millimeters to make up 1 meter.0131

Milli means 1000, but in a small way also.0140

It takes 1000 of these very small units to make up 1 meter.0143

Kilo also means 1000, but in a big way.0152

That means it takes 1000 meters to make up 1 kilometer.0157

We know kilometer is bigger than the meters because it takes 1000 of these to make up 1 of those.0164

Let's go over the next one, mass, which is looking at weigh, how heavy something is.0177

1 pound is the same as 16 ounces; 1 ton is equal to 2000 pounds.0184

Depending on what you are weighing, you are going to use these different measurements.0194

If you are going to weigh something that is really, really light, then you are probably going to use ounces.0200

Pounds we know.0206

Tons would be something very heavy; like maybe a car or something that is pretty large, pretty heavy.0209

Kilogram which is kg; remember kilo; kilo means 1000, but in a big way.0219

It takes 1000 grams to make 1 kilogram.0231

A kilogram, again, anything with kilo means 1000; that is also used for mass.0238

For liquid, 1 gallon is the same as 4 quarts.0253

1 quart is the same as 2 pints; 1 of those is the same as 2 cups.0260

For this, there is... let's look at this.0269

I am going to show you an easy way to remember these.0276

I am going to write a G for gallon; let me write this part over.0281

Let's see; I have a G like that; G for gallon; this is 1 gallon.0294

Then since 1 gallon is equal to 4 quarts, I am going to write 4 Qs in here.0300

1, 2, 3, 4; that means 4 quarts; 4 Qs is equal to 1 gallon.0306

Within the Qs, I am going to write 2 Ps because I know that 2 pints is equal to 1 quart.0320

Here is P, P, P, P, P, and then there we go.0327

I have 2 Ps within 1 quart, 1 Q.0341

Then 1 pint is equal to 2 cups.0346

Within each P, I am going to write 2 Cs.0349

We know G is for gallon, Q is for quarts, P is for pints, C is for cups.0366

If I ask you how many pints are in 1 gallon,0373

you can just count how many Ps there are within the G for the gallon.0379

1, 2, 3, 4, 5, 6, 7, 8; there are 8 pints in 1 gallon.0386

What if I ask you how many pints are in 2 quarts?0392

You are going to count all the Ps within 2 Qs.0396

It is 1, 2, 3, 4.0400

How many cups are in 1 quart?0402

1, 2, 3, 4; there is 4 Cs in 1 Q.0406

You can just use this to help you when it comes to the liquid measurements.0411

When we convert these, if I want to convert meters into centimeters,0423

first of all I have to know the measurement of 1 meter equals how many centimeters?0430

Centi meant 100, but in a small way.0439

I know that 100 centimeters equals 1 meter.0444

I am just going to write that below here; 1 meter equals 100 centimeters.0448

This is just an easy way to do this.0455

We are going to probably cover this again when we go over proportions and that chapter.0457

But for now, you can just write this below here just to help you.0463

From meter, 1 meter was the same as 100 centimeters.0471

To get from 1 to this, you multiplied by what?--by 10; multiplied by 10.0478

In the same way, I have to take 100.0487

Then multiply it by 10 to get how many centimeters is going to be equal to 10 meters.0491

Whenever I take this number and multiply it by 10,0499

there is just one 0 for 10 so I can just add a 0 there at the end of it.0505

It is going to be 1000; 100 times 10 is 1000.0510

I know that 10 meters is the same as 1000 centimeters.0514

Quarts to cups; if you don't remember how many cups is equal to the pints and the quarts,0523

you can just draw your G and then use that as a reference.0531

Let me just write that out just so you guys can see it.0538

Remember I had 4 Qs; within each Q, I had 2 Ps.0542

Within each P, I had 2 Cs.0550

1 quart, 1 Q, how many cups do I have?0555

I have 4Cs; I have 4 cups; 1 quart is the same as 4 cups.0560

Yards to inches; I know that 1 yard is equal to 3 feet.0575

1 yard is equal to 3 feet; 1 feet is equal to 12 inches.0592

If I want to go from yards to inches, since I know that 1 yard is 3 feet0605

and only 1 of these is equal to 12 inches,0614

to get from here to here or from here to here, you multiplied by 3.0618

Then if I want to go from inches to yards, I have to multiply by 3.0625

12 times 3 is 36; 1 yard is equal to 36 inches.0635

I know this seems a little confusing.0645

But I just know that I have the top and the bottom.0646

To get from 1 to 3, you have to multiply by 3.0653

You have to multiply this side also by 3 to get back to the yards.0659

1 feet is equal to 12 inches; 3 feet is going to be 36 inches.0666

3 feet is the same thing as 1 yard.0672

So you can look at it that way.0674

Ounces to pounds; I know that 16 ounces is equal to 1 pound.0678

How did you get from 16 to 8?0694

Once these are the same, you can just convert it back over.0701

To get from 16 to 8, I divided by 2.0706

I have to also take this number and divide by 2.0714

I have to do the same thing to both sides.0719

1 divided by 2 is 1/2; this means 1 divided by 2.0722

1/2 is the same thing as 1 divided by 2.0732

8 ounces is half a pound.0734

Few more; 2 yards equals how many feet?0741

I know that 1 yard equals 3 feet.0747

Again I have yard to yard, feet to feet.0756

To go from 1 to 2, I multiplied by 2.0762

Then I have to do the same thing on this side.0771

Multiply by 2; take this number; times 2 is 6.0774

2 yards is the same as 6 feet.0781

Now 8 quarts to how many pints?0790

1 quart equal to 2 pints; 1 quart is equal to 2 pints.0794

Again I have quarts to quarts and pints to pints.0807

How do I go from 1 to 8?--you multiply.0812

It is always going to be multiplication or division.0817

You are not going to add 7 to get 8.0819

You don't do plus and minus; you are going to do times and divide.0822

1 times 8 is 8; then I need to multiply this by 8 which is 16.0827

8 quarts is equal to 16 pints.0839

Let's do a couple more; 1 gallon equals how many pints?0844

You can draw your G again.0853

Let's draw a big G so you guys can look at it, G for gallon.0855

I know that 4 quarts equals a gallon; you just draw this over.0862

Within each quart, there are 2 pints.0870

Since I am only going up to pints, I am not using cups.0883

I don't have to draw the Cs in there.0886

Within 1 G, how many Ps do I see?0890

I see 1, 2, 3, 4, 5, 6, 7, 8.0894

In 1 gallon, there are 8 pints.0899

Then 2 kilometers equals how many meters?0908

Remember kilo means 1000 in a big way.0912

I know that there is going to be a lot more meters than kilometers0918

because since kilometers are big, it means 1000 in a big way,0922

there has to be more meters to make up for the kilometer.0928

1 kilometer equals 1000 meters.0934

Again this is kilometer to kilometer and meters to meters.0943

I can just go ahead and see what I multiplied this by.0947

1 times 2 equals 2.0953

You have to multiply this by 2 to get the 2 kilometers.0957

You are going to do the same thing on this side.0961

You have to also multiply by 2; take this number; 1000 times 2 is 2000.0962

2 kilometers is 2000 meters.0972

If you need to, go back to the beginning of this lesson and review over the different units of measurement.0978

Try to get yourself familiar with all of them.0984

That is it for this lesson on units of measurement.0989
