Get Dimensional Analysis Practice Problems

Set up each problem by writing down what you need to find with a question mark. Then set it equal to the information that you are given. The problem is solved by multiplying the given data and its units by the appropriate unit factors so that only the desired units are present at the end.

For example, a mass measured in grams may be more convenient to work with if it was expressed in mg (10–3 g). Converting between metric units is called unit analysis or dimensional analysis.

Performing dimensional analysis is a pretty easy process. All you have to do is set up a series of fractions where the units end up canceling out. Remember, when you have fractions and want something to cancel out, you have to make sure it is present in both the numerator and denominator.

Answer and Explanation: There are 259,200 minutes in 180 days. To do this conversion, you need to start with the number of minutes in one day. There are 60 minutes in one hour and 24 hours in one day, so to find the number of minutes in one day, multiply 60 x 24.

Dimensional Analysis Identify the given (see previous concept for additional information). Identify conversion factors that will help you get from your original units to your desired unit. Set up your equation so that your undesired units cancel out to give you your desired units.

Dimensional analysis, also known as factor-label method or unit-factor method, is a method used to convert one unit to a different unit. To do this, we make use of a conversion factor, which is a numerical quantity that we multiply or divide to the quantity or number that we want to convert.
