18 deg Celsius = 64.4 deg Fahrenheit.
Temperature is easy to convert from Fahrenheit to Celsius yourself. You can use the formula Tc = (5/9)*(Tf-32) where Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit. 65 F is 18 C.
-18 degrees Celsius = -0.4 degrees Fahrenheit
18 degrees Celsius = 64.4 degrees Fahrenheit.
It would have to rise 18 degrees Celsius.
18 degrees Celsius minus 25 degrees Celsius equals -7 degrees Celsius.
20 degrees Celsius is colder than 18 degrees Celsius.
-18 degrees Celsius is colder than -12 degrees Celsius. The lower the temperature in degrees Celsius, the colder it is. In this case, -18 degrees Celsius is 6 degrees colder than -12 degrees Celsius.
27.6
-7.78 degrees Celsius.
-10 C = 32 + -10 x 9/5 = 32 - 18 = 14 F greater than 10 F
-18 degrees Celsius is equal to 0.4 degrees Fahrenheit.
18 degrees Celsius is already in the Celsius scale. There is no conversion needed as Celsius and centigrade are the same.
