Judging Fahrenheit and Celsius Temperatures
Date: 03/31/2004 at 22:56:22 From: Kenya Subject: I just don't get anything about TEMPERATURE Dear Doctor Math, Temperature is so confusing! I'm doing temperature in class but I don't get it. I have a hard time judging if a temperature would be hot or cold. For example, here's a question from our math text book: You decide to wear a jacket outside. What is the temperature most likely to be? A: 23C B: 54F C: 98F D: 98C I would choose D, but a lot of times I get it wrong. I am not just in fourth grade, But in 4th APPAS, a special class for smart kids. I'm afraid of being dropped down to the lowest section in my grade.

It's a little confusing that they include both Fahrenheit and Celsius temperatures in the problem; it's better to learn one system at a time. But you can look at each answer separately and think about whether it makes sense. You need to have some knowledge of typical temperatures, so you can compare. For example, in Fahrenheit 0 = very cold winter weather 32 = water freezes 68 = comfortable room temperature 100 = hot outdoor weather 212 = water boils Look at where 54F and 98F fit on this chart, and decide whether you would want to wear a jacket if you were outside in that temperature. Now do the same with the Celsius temperatures and this chart: 0 = water freezes 20 = comfortable room temperature 40 = hot outdoor weather 100 = water boils Can you see which answer makes sense now? Combining your intelligence and a little knowledge of facts (which smart people need to learn just as much as the rest of us), you should do fine.
