### 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 feet*0605

*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 kilometers*0918

*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

*Thank you for watching Educator.com.*0993

The story David refers to goes along with the Big G that Intructor Pyo drew for liquid measurement. The stores states the following: Once in the Kingdom of Gallon there lived four Queens. (The 4 Queens Ms. Pyro drew inside the Big G represent 4 quarts.) Each Queen had a Prince and Princess. (The 2 PS Ms. Pyro drew inside each Q represent 2 Pints.) Each Prince and Princess had two cats. (The two C's that Ms. Pyo drew inside each P represent cups.) The Horizontal line that Ms.Pyo drew on the G shows the division for a half gallon. This story and picture are sometimes taught to 3rd or 4th grade students as a memory device.
