Two of the most widely used systems to measure temperature are the Fahrenheit and Celsius scales. While the Fahrenheit scale is employed primarily in the United States, the Celsius scale is used in almost every other part of the world. Because conversion between the two scales is sometimes necessary, it is helpful to know how to convert temperatures such as 22.8 degrees Celsius to Celsius by using one of three simple equations.

## Instructions

1. 1

Insert the value of 73 for "Fahrenheit" in the equation Celsius = (Fahrenheit - 32) * 5/9. Substituting 73 results in Celsius = (73 - 32) * 5/9, which then becomes 41 * 5/9 and is finalised as approximately 22.7778, or 22.8 degrees Celsius.

2. 2

Substitute 73 for "Fahrenheit" in the alternate equation Celsius = (Fahrenheit - 32) / 1.8 and solve. This results in Celsius = (73 - 32) / 1.8, which becomes 41 / 1.8 and provides the result 22.7778, or 22.8 degrees Celsius.

3. 3

Convert 73 to Celsius by substituting "Fahrenheit" in the equation Celsius = (Fahrenheit + 40) * 5/9 - 40. Plugging in the value of 73 results in Celsius = (73 + 40) * 5/9 - 40, which becomes 113 * 5/9 -40, then approximately 62.7778 - 40, which equals approximately 22.7778, or 22.8 degrees Celsius.
