Get Chem Skills Worksheet 10 Dimensional Analysis

Dimensional Analysis is a way chemists and other scientists convert units of measurement. We can convert any unit to another unit of the same dimension. This means we can convert some number of seconds into another unit of time, such as minutes, because we know that there are always 60 seconds in one minute.

And then day at the bottom.

“Dimensional analysis” may sound complicated, but this is a method we use in everyday conversions, such as when figuring out how many gallons of gas we can get for $30 or how many donuts are in two dozen. Most unit conversions can be solved through dimensional analysis, also known as the factor-label method.

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.

Q-Chat Identify the starting factor. Identify answer units. Determine conversion factors needed. Ensure the conversion factors are in the correct format. Cancel units that appear in both the numerator and denominator. Simplify the fractions. Solve.

The main idea in Dimensional Analysis is to create a conversion ratio (unit factor) which has the units you want in the numerator and the units you already have in the denominator. It may be necessary to multiply by more than one conversion ratio in more difficult problems.
