Converting between Fahrenheit and Celsius temperature scales

The chart below will help you quickly make rough conversions between the Fahrenheit and Celsius temperature scales. To make more exact conversions, use the formulas below the chart.
Tc = Temperature in Celsius
Tf = Temperature in Fahrenheit

Tc = (5/9)*(Tf-32)

For example: 100 degree Fahrenheit

Tc = (5/9)*(100-32) = (5/9)*68 = 37.8

To convert Fahrenheit temperatures into Celsius:

Begin by subtracting 32 from the Fahrenheit number.
Then multiply that answer by 5.

Using an Algebraic Formula:

For the mathematically daring, here is the algebraic formula used for conversion from Fahrenheit to Celsius:

Tc=(5/9)*(Tf-32)
Tc=temperature in degrees Celsius Tf=temperature in degrees Fahrenheit
* means multiply

Now, to convert from Celsius to Fahrenheit,:
Tf=(9/5)*Tc+32
Tc=temperature in degrees Celsius Tf=temperature in degrees Fahrenheit
