Try the following problems, being very careful with units. Get into the habit of showing all units and how they cancel in every step of a calculation. Question 1: A piece of metal has a mass of 27.6 g and a volume of 6.72 mL.
In fact, the factor label method is all about units. Here's a simple example: suppose you’re told that the length of a pencil is 8.4 cm and you wish to determine its length in inches. You are told that 1 inch = 2.54 cm. You can solve this with the use of a conversion factor.

Do these unit conversion problems by the factor label method on the “Unit Conversion Examples” handout. We also used this method in class when we converted measurements in hands to centimeters. Be sure to show every step in the unit conversion process! Also, pay attention to significant figures.
In Engineering disciplines, we use the three-step Factor-Label Method of Unit Conversion to solve algebraic problems with mixed units. Step 1 Write the algebraic equation so the desired quantity is on the left of the equals sign, and an algebraic expression is on the right of the equals sign.
You should look at the question, work it out on paper (not in your head), before checking the answers at the end. The purpose of these problems is not merely to get the right answer, but to practice writing out the dimensional analysis setup.
In Engineering disciplines, we use the Factor-Label Method of unit conversion to solve problems with mixed units. There are three steps to this method: Step 1 Write the problem algebraically so the desired quantity is to the left of the equals sign, and an algebraic equation is to the right of the equals sign.
