Unit Conversions
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.
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
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
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
