Selected answers to common questions:
    Celsius to Fahrenheit.

Adding and Subtracting Negative Integers as Temperatures [01/08/2004]
If it's -20 degrees outside and it decreases 3 degrees what temperature is it? I know the answer is -23 degrees but it seems like it should be -17 degrees.

Celsius and Fahrenheit Conversions [09/15/1997]
For what value of C do both scales represent the same temperature?

Celsius to Fahrenheit [04/26/1999]
How do you convert Celsius to Fahrenheit?

Changing Celsius to Fahrenheit [9/9/1996]
How do you change Celsius to Fahrenheit?

Converting between Celsius and Fahrenheit [06/23/2009]
How can I use algebra to derive the unusual temperature conversion formulas F = 9/5(C + 40) - 40 and C = 5/9(F + 40) - 40 ?

Converting Celsius to Fahrenheit [2/28/1996]
What is the Fahrenheit equivalent for 15 million degrees centigrade? (That's the temperature at the center of the sun.) What is the Fahrenheit equivalent of -150 degrees Celsius, and how does this differ from centigrade? To convert 500 degrees centigrade to Fahrenheit, what figures do I use?

Converting Celsius to Fahrenheit and Why It Works [04/03/2004]
What are the Fahrenheit and Celsius patterns that will help me predict Fahrenheit temperature based on the Celsius temperature?

Converting Fahrenheit to Celsius [9/29/1995]
Is there a temperature that is the same on both the Celsius and Fahrenheit scales?

Degrees Kelvin [04/16/2002]
Why is it considered to be wrong to write, for example, 0 degrees Kelvin?

Derive the Function of Celsius to Fahrenheit [09/22/1997]
How do you get the equation of Celsius to Fahrenheit and vice versa? How would you graph that function?

Deriving the Celsius-to-Fahrenheit Conversion Formula [12/03/2001]
What is 27 degrees Celsius above freezing in Farenheit?

Dimensional Analysis and Temperature Conversion [04/13/2002]
I understand that you can use cross multiplication to find how many centimeters equal a certain number of inches, but I get confused when I try to apply the same logic when converting from Celsius to Farenheit.

Doubling Zero? [02/13/2007]
I have a student who asked, 'What is twice as cold as zero?'

Equivalent Temperatures, Different Scales [05/28/2003]
The inhabitants of Xenor use two scales for measuring temperature. On the A scale water freezes at O degrees and boils at 80 degrees; on the B scale water freezes at -20 degrees and boils at 120 degrees. What is the equivalent on the A scale of a temperature of 29 degrees on the B scale?

Kelvin Scale [08/20/2002]
I need to know about the kelvin scale, and how to convert from kelvin to Celsius.

Minus Temperatures, Minutes Before [12/07/2012]
A student gets confused by the rate of change of temperature that dips below zero Celsius, as measured before a certain time. After graphing the time and data points, Doctor Ian makes an analogy to a more familiar rate of change.

Origins of Celsius and Fahrenheit [03/31/2002]
Who invented Celsius and Fahrenheit?

The Origins of Fahrenheit [09/16/1998]
Why did Fahrenheit decide to make 32 degrees his freezing point and 212 degrees his boiling point?

Origins of the Fahrenheit Scale [11/20/1998]
Why did Fahrenheit choose 32 as the freezing point of water? Where did he get his scale?

Spaces and the Number Line [02/26/2003]
If you say, 'How many degrees are there between -2 and 4?' would you count the 0 degrees and answer 7 degrees or would you not count the nought and answer 6 degrees?

Temperature Difference [05/20/1999]
Can 44 degrees Centigrade equal 80 degrees Fahrenheit when you are talking temperature difference?

Twice as Cold as Zero [04/28/1999]
What is the temperature if it's twice as cold (or warm) as zero degrees?

Where did Fahrenheit and Celsius Come From? [07/26/1997]
How did scientists figure out the relation between two numbers that mean the same thing, e.g. 0 deg C and 32 deg F?

Zero Point of Thermometer [04/06/2002]
What is the zero point of a thermometer? Is it 0 degrees of any temperature scale, or 0 Kelvin, or -273.15 Kelvin?
