Lesson 41 Temperature Conversions

Formula page

I expect that you will be able to use a formula page for this class,  but that will be determined by your teacher.

Your teacher may have a formula page they expect you to use.

Below is a link to the formula page I will use (at least for now!) when I’m doing questions for this class.

This may change, depending on feedback from your teacher.

I encourage you to download this page and print it so you have it handy when you are doing math.

Step 1   What is temperature?

Temperature is a numerical representation of hot or cold compared against baselines,  typically the point at which water freezes and boils.

I.E.   a NUMBER that represents how hot or cold something is,  compared to recognizable benchmarks,  the temperature of freezing or boiling water.

Step 2   Thermometers
