**The temperature 19 degrees Celsius is 66.2 degrees Fahrenheit.** The equation for converting Celsius to Fahrenheit is F=(9/5)*C+32, or degrees Celsius multiplied by nine, which is then divided by five and added to 32. To convert Fahrenheit to Celsius, the equation is C=(5/9)*(F-32).

Celsius and Fahrenheit are two ways of measuring temperature. The Celsius scale was developed by Anders Celsius in 1743 by anchoring the freezing point of water at 0 degrees and the boiling point at 100 degrees. This scale is commonly used in most of the world and in the scientific fields. The Fahrenheit scale was created in 1724 by Gabriel Fahrenheit. He anchored the boiling point of water at 212 degrees and the freezing point at 32 degrees. As of 2014, the United States, the Cayman Islands, Belize and the Bahamas officially use the Fahrenheit scale.
