How to Convert measurements
Dec 7, 2021
Welcome to math with mister J in this video, we're going to be taking a look at converting customary units of length. And the units of length that we're going to be using are feet, inches, yards, and miles. And as you can see, there are 8 problems or 8 conversions that we're going to go through together in order to help you get this down. So let's jump right into number one here, where we have two feet equals how many inches. And before I go any further, I want to mention up top and blue at the top of your screen are some very helpful reference notes here that you can use to take a look at when you're doing conversions. So let's take a look at number one, two feet, how many inches? While we know that one foot equals 12 inches, right? Think of a ruler, a ruler is 12 inches. So if you have two of those, we would have 24 inches. We need to do two feet, times 12, right? We have two groups of 12 inches, which would give us 24 inches. So when we go from a larger unit of measure, a foot is larger than an inch, when we go from larger to smaller, we multiply. So keep that in mind. Number two, we're going from inches back to feet. So now we have 48 inches equals how many feet. Well, if we think about it, we need to split this 48 inches in the groups of 12, because each one of those groups of 12 is a foot. So we're going to need to do 48 divided by 12. And 48 divided by 12 gives us four feet. And we went from a smaller unit of measure inches to feet, so we used division. A smaller unit of measure to a larger we use division. So for number three, we have 6 yards equals how many feet. While one yard equals three feet, so we have 6 of them. So we need to multiply this by three. So 6 times three equals 18 feet. And think of a yardstick, a yardstick has three feet, so if we had 6 of them lined up, it's going to be three plus three plus three plus three plus three plus three. I think I got 6 there, which it's just easier to do 6 times three, and that's 18. Number four, 24 feet equals how many yards. So now we're starting with feet and going to yards, so we need to split that 24 feet into groups of three, or we can think of it as dividing it by three. And 24 divided by three is 8. And you can always double check yourself by going back to feet. Let's see if 8 yards is 24 feet. Well, 8 times three does give me 24 because each one of the each one of those yards is three feet, so I could do 8 times three. And again, it gives me that 24. Number 5, 5 feet equals how many inches. Well, each one of those feet has 12 inches. Right, I have 5 groups of 12. So I'm going to do 5 times 12, which gives me 60 inches. Number 6, 6 feet equals how many yards? So think how many how many feet in one yard? Well, three. So how many groups of three can I pull out of that 6 feet? Or think of it as 6 divided by three. And that's going to give us two. So 6 feet equals two yards. Two yards equals how many inches. Well, if we take a look up here at the top, one yard is 36 inches. Which is three one yards the same as three feet. So 36 inches. So we need to do two times 36. Two groups of 36. And if you think of it, a yardstick is 36 inches. So we have two of those. So two times 36, which is 72. Inches. And lastly, miles to feet. So one mile equals 5280 feet. So we have two groups of that two groups of 5280. So we need to do 5280 times two. Or you could do 5280 plus 5280. So we would get. 10,000 560 feet. I don't think I can fit it in that space there, so I will draw an arrow. So there you have it. There's converting customary units of length involving feet, inches, yards, and miles. Hopefully that helped. Thanks so much for watching until next time, peace.
