Temperature

To convert degrees Fahrenheit (°F) to degrees Celsius (°C), subtract 32° and multiply by 5/9 or

0.5556.
Example: (45.0°F - 32°) x 0.5556 = 7.22°C
To convert a temperature range (that is, a range of 10°F) from Fahrenheit to Celsius, multiply by 5/9

or 0.5556.
Example: 10.0°F range x 0.5556 = 5.6 °C range
