In this topic, we will start to think about some general modeling concerns, before we Dimensional analysis for converting. Dimensional analysis for proportional reasoning. Word problems with multiple units of distance units over time units, which corresponds to the formula v =d/t. Reasonable inferences from estimates.

Translate into math terms—writing them all down can't hurt: Pick a starting factor. Almost enough, but how can you get from teaspoons to gallons? The point of this example is to remind you that dimensional analysis is applied math, not abstract math. What do you know that you might need to use? What are you given by the problem, if anything? Understanding is more durable than memory.

Write it all down in math terms and see what you have:. But knowing the right answer is not enough. Exact answers can only be obtained if you use conversion factors that are exactly correct. What do you want to know? How can this be?
Finally add the units that are left over to the number to get the answer you wanted. If you set up the bridge so the units work out, then, unless you push the wrong button on your calculator, you WILL get the right answer every time. We're talking about measurable stuff, stuff you can count. If you can't solve the problem, pick a different starting factor and start. Dimensional analysis also known as the factor-label method or unit-factor method is by far the most useful math trick you'll ever learn.
