This three page, 19 question, worksheet requires to convert unit rates using dimensional analysis to different units of measure. The worksheet is broken into 3 levels: bronze, silver, and gold. The bronze and silver levels require students to convert within one system of measure. The gold level requires students to convert between the customary and metric systems. The bronze level questions can be solved using one step to convert. The silver questions may take two or three steps to convert. The gold questions will take multiple steps. This differentiated worksheet will keep your students engaged and eager to move from one level to the next (and your administration happy that you are differentiating for both your weak and strong students).
