What is the change in average temperature between January and July if January's average temperature is 9 degrees Celsius and July's average temperature is 16 degrees Celsius in America?

The change is 7 Celsius degrees (NOT degrees Celsius).

A substance has a temperature change from 20 degrees celsius to 45 degrees celsius. This corresponds to what temperature change in Fahrenheit degrees?

20 degrees Celsius is 68 degrees Fahrenheit. 45 degrees Celsius is 113 degrees Fahrenheit. So 25 degrees change Celsius = 25 x 1.8 = 45 degrees Fahrenheit. 1 degree change in Celsius is equivalent to 1.8 degrees change in Fahrenheit.

How many degrees in Fahrenheit is in 7 Celsius?

A change of 7.2 degrees on the Fahrenheit scale would be a change of 4 degrees on the Celsius scale. The conversion is 1.8 Fahrenheit degrees per Celsius degree (Celsius degrees are larger intervals).Example :[ Temperature in °C = 5/9 (temperature in °F - 32°) ]86° F is equal to 30° C93.2° F is equal to 34° C
