If you’re a long time Subscriber to MOST — and we have many Subscribers that joined us on our former blogspot site over three years ago! — you have heard this sermon before: The MOST important math skill you can bring to the certification exam is the ability to perform conversions.
How many gallons in a cubic foot? How many million gallons in a storage tank? How many cubic yards of excavation? The list is endless. In fact, there is not one single math problem you will encounter where conversions are not a major factor.
The best way to address conversions is with a standard procedure known as Unit Dimensional Analysis. That term is pretty scary, but the procedure is very simple. In fact, it only has three steps:
1. Start with what you know
2. Divide by 1
3. Multiply by 1
We’re confident you can remember those three steps! For a quick look at this procedure, go to the MOST YouTube site:
While you’re there, become a Subscriber to our YouTube site too. You are not automatically a Subscriber there just because you are a MOST Subscriber!
If you like what you see, and you realize you need more practice with Unit Dimensional Analysis, please try our MOST Water Math course WM-1. We spend a full hour going over this procedure, and go step-by-step through 25 separate example problems. After this one hour course, you’ll be ready to tackle any conversion problem you will face on the certification exam. It’s only $10, and you can replay it as many times as you like for up to a full year. And it’s available online right now here at MOST!
As we’ve said before, this is your best friend in Water Math.
