![]() ![]() Mommyo, pointedly: “They are all even numbers.” But you have to do all the even-numbered ones.” The Nine-Year-Old, grudgingly: “Oh all right. We’ll keep that chart next to our Galileo thermometer so that we can know what all the labels mean.” Let’s do all the math one time and use it to make a chart. The Nine-Year-Old: “But no one speaks it here.” The Nine-Year-Old, sadly: “Mommyo, do I really have to do all that math every time I want to use the Galileo thermometer?” If the Galileo thermometer reports a temperature of 24☌ in Mommyo’s office, what is the temperature in Fahrenheit?ħ5.2☏ feels about right, actually. Or, if you prefer the math:Ĭlear as mud? Let’s do a sample problem. First subtract 32, then multiple by 5, then divide by 9. *Fun Fact: To convert from Fahrenheit to Celsius, you do the reverse. To convert from Celsius to Fahrenheit, you multiply the temperature by 9, then divide by 5, and add 32.* There are entire web pages devoted to eliminating that little bit of math from our lives.īut here at Caterpickles, we believe that the easiest road isn’t always the best road, even when Math is involved, so here’s the math behind those temperature conversion tools. These days, the absolute easiest way to convert from Celsius to Fahrenheit is to Google it. “How do I convert temperatures from Celsius to Fahrenheit?” We live in a Fahrenheit world here at Caterpickles Central, so 24☌ doesn’t really mean much to us. ![]() The label on the lowest bubble tells you the temperature.Īs I type this, the label on my lowest floating bubble reads 24☌.Īll the labels on our Galileo thermometer are written in Celsius. To read a Galileo thermometer, look at the bubbles floating near the top of the tube. So I decided that this would be the week The Nine-Year-Old and I finally learn to use the Galileo thermometer Daddyo gave us all those years ago. Photo: Shala HowellĪs you can see, our storm glass still isn’t back to normal after all the experimenting we’ve been doing on it. The shorter tube on the right is the slowly recovering storm glass. The tall thing on the left is a Galileo thermometer. ![]()
