How To Read A Thermometer

In this digital world it’s so easy to ask Google, Siri, or Alexa, “What’s the temperature outside? The Bear adventure, Bear Necessities, has us learning how to read a thermometer.

Depending on the part of the world, culture, or profession, you will either read your thermometer in Celsius or Fahrenheit. The United States is one of the only few countries to use Fahrenheit. Most of the world uses Celsius to record temperature. When I use to work in food, we had to calibrate our thermometers to be 32° by placing the food thermometer into a glass of ice water. When comparing Fahrenheit to Celsius, both 32 and 0 are freezing points.

The traditional analog thermometer with the red bubble on the bottom has been used for many years. Usually on one side you can read the temperature in Celsius while the other side has Fahrenheit. As the temperature rises and lowers, the red meter will reflect. The absolute top of the red will give you your temperature. In the above image the temperature is about 76 degrees Fahrenheit.

The above pictured thermometer is another analog version. This type of thermometer will give you the read out at the tip of the arrow. This thermometer also gives you both Celsius and Fahrenheit.

The last thermometer that we will take a look at is our digital thermometer. This one is extremely simple. The digital read out is very clear of what the temperature is. This weather station gives us not only the temperature outside, but also the temperature inside, the relative humidity, date, time, and moon phases. You usually will need to select between Fahrenheit of Celsius by switching between the two on the back of your weather station.
