  1. 2479 mg = _______________ g
    You are moving from a small unit to bigger one, so you must move the decimal to the left or divide when converting.


Place your finger on the milli box. Count until you reach the basic unit box, which in this case represents grams. You have counted to 3 therefore, you must move the decimal 3 places to the left.

2479 / 1000 = 2.479

There are 1000 milligrams in a gram. Therefore you must divide 2479 by 1000.

 

  1. 79.346 L = _______________ cL
