Conversions

Are you failing Chemistry already? Conversions are the main reason people struggle in Chemistry. People seek help when converting common conversion factors together like centimeters and inches. Struggling is now a thing of the past because I have a proven method that guarantees a better understanding of conversions. 

Say you want to know how many seconds old you will be the second you're fifteen. The majority of students will mistakenly figure this out the long way by adding up the seconds in the number of minutes in a year or some other complicated way. To figure that out, you must understand the amount of seconds in a minute, the minutes in an hour, the hours in a day, and the days in a year. 

Rule: Place the conversion unit you have on top and the conversion unit you aim for on the bottom. Ex: 1 foot on top, 12 inches on the bottom.

As you can see in the demonstration above, I started off with the amount I have, which is 15 years. Then I multiply by a fraction. 

• In this fraction I put the conversion I have on top, which is years, and place the conversion I want to get to on the bottom, which is days. The fraction has to be equal. In other words, the top has to equal the bottom. So 1 year equals 365.25 days and that's why 365.25 days is on the bottom. 
• Then I multiply by another fraction where I place the conversion unit I have(day) on top and the conversion unit I want on the bottom. In this case I want hours so I put 24 hours because it is equal to a day. 
• Then I multiply by another fraction where I place the conversion unit I have(hour) on top and the conversion unit I want on the bottom. In this case I want minutes so I put 60 minutes because it is equal to an hour. 
• Then I multiply by another fraction where I place the conversion unit I have(minute) on top and the conversion unit I want on the bottom. In this case I want seconds so I put 60 seconds because it is equal to a minute. 

The hard part is done and now the easy part comes in. Now you get to multiply across and get your answer. Try it!
