### Converting Units

1. 1. Unit Conversions
2. 2. How Do We Convert Units? 1) 2) You need a conversion factor Use the conversion factor to get the units you want Example: You know something is 83 feet long, and you want to know how many meters that is. First, find the conversion fact that has BOTH feet and meters  in 1 m there are 3.28 feet Our conversion factor is 1m/3.28ft 83 ft X 1m/3.28 ft  25.30m USE THE UNITS TO GUIDE YOU! Always show your work in my class. Cross out the units to make sure you are correct.
3. 3. Practice (Yes, you can use calculator/phone) Convert 137 cc to L (liters) Conversion factor: in 1 liter, there are 1000 cc  1L/1000 cc 137 cc X 1L/1000 cc  0.137 L
4. 4. Practice (Yes, you can use calculator/phone) Convert 2373 seconds (s) to days Conversion factor: in 1 day there are 86400 seconds  1 day/86400 s 2373 s X 1 day/86400 s  0.02747 days
5. 5. Practice (Yes, you can use calculator/phone) Convert your age to minutes (round your age to the nearest year) Conversion factor: in 1 year there are 525949 minutes 1 year/ 525949 min 40 years X 525949 min/1 year  21,000,000 minutes Worksheet….. SHOW ALL YOUR WORK, and ALWAYS WRITE THE UNITS AT THE END.
