Unit ConversionsThis is a featured page

Definition: To change one unit of measurement to another.

Explanation/Notes:
  • Example: 138 eggs= 11.5 dozen
  1. Write down what you need and put it over 1.
  2. Decide which conversion to use.
  3. Losers will go on the bottom and winners will go on the top. Losers are the term that we want to lose and winners are the term we want to convert to. Since we need to get rid of eggs, they are the losers. Since we need our answer to be dozens, they are the winners.
  4. Cancel the units from the losers.
  5. After you have the winner on top, it is time for the math! Multiply everything on top together and then multiply everything on the bottom together. Finally, simplify the fraction by dividing the number on the top by the numer on the bottom.
  • Two factor unit conversions- Remember one factor conversions changed only one starting and one ending unit (hours to minutes, etc...). One factor multiple steps were just a series of single factor conversions (hours to minutes, then minutes to seconds etc...)
  • With two factor conversions one can change two differing starting units into two differing ending units.

Formula:
  1. 144 yrs 365 days
    1 1 year
  2. Then you cross our years because they are the "losers" and after you multiply you get 52,560 day

Units: miles,feet,dozen,gallon,kilometer,days,yards,centuries,and minutes
*note there are more units,these are just the most common*


Everyday Example: To find out how many liters are in a gallon and how many miles are in a certain amount of feet.
