Temperature confusion

As an American, do you ever get confused about the Celsius to Fahrenheit or vice versa?  I am currently in the process of learning.  I of course learn about it during school, but never really paid much more attention to it, then reading it and writing it down in Science classes.

I figured out that:

• Every Celsius degree is 1.8 degrees Fahrenheit
• Every 5 Degrees Celsius is 9 degrees Fahrenheit

I feel kind of stupid just now attempting to fully understand the different measurements. I'm sorry, but the Metric system just seems smarter in measurements.

Do you have any tips on learning? Will this help you learn the difference?
