Two scales are used to measure temperature.  The Celsius scale, part of the metric system, was invented in 1741 by Swedish astronomer Anders Celsius (1701-1744).  The Celsius scale has the freezing point of water at 0° C.  The scale most frequently used in the United States is the Fahrenheit scale, invented in 1714 by German physicist Gabriel Daniel Fahrenheit (1686-1736).  On the Fahrenheit scale, the boiling point of water is 212°F, and the freezing point is 32°F. 
To convert Celsius temperatures to Fahrenheit, use the formula F= 9/5C + 32.
  • Using the formula, convert the average temperatures of Mars, Earth, and Venus from Celsius to Fahrenheit.  How do the temperatures compare?
  • The greenhouse effect may raise the average temperature of Earth 8°F by the year 2050.  What will be the average temperature of Earth in degrees Celsius at that time?
  • Change the formula for converting Celsius to Fahrenheit to a formula for converting Fahrenheit to Celsius.
