-18°C = -0.4°F
-18°C multiplied by 1.8 +32 = -0.4°F
18 deg Celsius = 64.4 deg Fahrenheit.
18 deg Celsius = 64.4 deg Fahrenheit.
It is 64.4 deg F.
-18 degrees Celsius = -0.4 degrees Fahrenheit.
18ºC = 64.4ºF
-18 degrees Celsius = -0.4 degrees Fahrenheit
18°F The degree intervals on the Celsius scale number 100 between the freezing and boiling points of water (0° and 100°), whereas there are 180 intervals between them in the Fahrenheit scale (32° and 212°). So the conversion between scales is 1° C = 1.8°F (9/5°). A change of 10°C is equal to a change of 18°F. (10x1.8=18)
The Celsius and the Fahrenheit scale don't run parallel. 18 deg C is about normal room temperature. Water will always be liquid at 18 deg C wherever you are.
86 deg F = 30 deg C So the temperature has changed from -18 deg C to 30 deg C, an increase of 48 deg. Conversely, -18 deg C = -0.4 deg F So the temperature has changed from -0.4 deg F to 86 deg F, an increase of 86.4 deg.
Fahrenheit = (Celsius x 9/5) + 32 = (18 x 9/5) + 32 = 64.4 degrees Fahrenheit Watch for the correct spelling of Fahrenheit and Celsius. Scroll down to related links and look at "Conversion of temperatures and formulas".
The difference between two degrees on the Celsius scale is equal to (9 / 5) x 2 = 3.6 degrees on the Fahrenheit scale. For example, 20 degrees Celsius is equal to 68 degrees Fahrenheit, while 22 degrees Celsius is equal to 71.6 degrees Fahrenheit. Similarly, a temperature decrease of 2 degrees Celsius would equal a difference of 3.6 Fahrenheit. 18 degrees Celsius is equal to 64.4 degrees Fahrenheit.
18 degrees Celsius = 64.4 degrees Fahrenheit.
