65How to calculate Measurement ConversionsClick here next slide

7Hint1 kilogram = 2.20 pounds.

Multiply 23 x 2.20

back1 kilogram = 2.20 pounds.

Multiply 23 x 2.20

64Why do we convert units?Measurements that are very big or very small are more difficult to work with

0.0000000000764 X 0.000321 = ?142,000,000,000 X 62,000,000 = ?654,321,000,000,000,000 / 12 = ?0.0000345 / 21,000,000= ?

5Why do we convert units?Comparing measurements is much easier when the same unit is used

3 miles > or < 9 km?Is 3800 seconds more than 1 hour?Youre how many minutes old?Is 4 tons a lot of grams?9 lbs or 200 oz?

6Lets practice by converting from Km to AU*dont forget that:1 au = 150,000,000 Km25

The first thing you need to decide is are you converting in the Metric system or Customary system of measure.Click here next slide

8If you are converting time the measurements are the same in both systems.60 seconds (s) = 1 minute (min)60 minutes (min) = 1 hour (h)24 hours (h) = 1 day (d)7 days (d) = 1 week (wk)52 weeks (wk) = 1 year (yr)12 months (mo) = 1 year (yr)365 days (d) = 1 year (yr)Back to Menu

17Here is an exampleIt took Sarahs family 3 days to drive from Meriden, CT. to Miami, Florida.How many hours did it take her family to complete the trip?Click here next slide

18IntroductionMain MenuHow to.The AUThe Solar SystemLets PracticeQuiz Time2We know that there are 24 hours in one day.Here is an exampleWe know it took Sarahs family 3 days.To figure out how many hours the trip took, we have to multiply 24 by 3. Once you complete the calculation, you find out that Sarahs family took 72 hours to make the trip.Click anywhere for next stepClick for second example

19Now you try one.Peter flew from Tampa, Florida, to New York City. His plane left Tampa at 6:34 A.M. and the flight took 3 hours 55 minutes. How many seconds was the flight?Click to solve

201 Astronomical Unit (AU)= 150,000,000 Km (or the average distance from the Earth to the Sun)

SunEarth|----------------------------| 1 Astronomical Unit(AU)

23Sun to Mercury = 57,900,000 Km

SunMercury|-----------| ? AU

How is it done?I can do it26

SunMercury|-----------| ? AU

Divide the distance from the sun to mercury (57,900,000 km) by the distance of 1 AU (150,000,000)57,900,000 / 150,000,000 = ?

27

SunVenus|---------------------| ? AUSun to venus = 108,200,000 Km

How is it done?I can do it

30

SunVenus|---------------------| ? AU

Divide the distance from the sun to venus (108,200,000 km) by the distance of 1 AU (150,000,000)108,200,000 / 150,000,000 = ?
