Converting Temperatures
In Section 1, you learned that most of the world uses the Celsius temperature scale, but that in the United
States, the most common temperature scale is Fahrenheit. You are probably more familiar with one of these
scales than the other. One way to become more comfortable with the unfamiliar temperature scale is to
compare the numerical values of everyday temperatures in ºC and ºF. a method for converting between
Celsius and Fahrenheit temperatures is given below.
To convert ºF to ºC
1. Subtract 32.
2. Multiply by 5.
3. Divide by 9.
To convert ºC to ºF
1. Multiply by 9.
2. Divide by 5.
3. Add 32.
Convert the following temperatures using the methods described above.
1.
Normal body temperature is 98.6ºF.
_______________________ºC
2. Room temperature is about 72ºF. __________________________ºC
3. The lowest temperature ever recorded on Earth was -89.4ºC at Vostok, Antarctica..
____________ºF
4. The highest temperature ever recorded on Earth was 57.8ºC at El Azizia, Libya.
_______________ºF
5. -40ºC = _______ºF
6. The common temperature for baking a cake is 350ºF. _______________ºC
7. Iron melts at 1535ºC. ________________ºF
Answer the following questions in the spaces provided.
8.
Which is warmer, -30ºC or -30ºF? Show your work.
9.
You are riding to school on the bus in a snowstorm. Through the window, you see a lighted sign
that gives the temperature as 26º, but you can’t make out whether the temperature scale is Celsius or
Fahrenheit. Which is it, and how do you know?
