40 F is 40 degrees Fahrenheit, that's what the F next to the 40 represents. Also, 40 F = 4.444444444444445 degrees Celsius or 4.445 C The formula for the conversion can be found here: http://wiki.answers.com/Q/What_is_the_conversion_formula_between_Celsius_and_Fahrenheit
-40 degrees Celsius is equal to -40 degrees Fahrenheit.
385 Fahrenheit = 196 Celsius
40 degrees below zero Celsius is equal to -40 degrees Fahrenheit.
Conversion: 40°C = 104°F
1 c = 33.8 f
122 degree Fahrenheit = 50 degree Celsius.
104ºF = 40.0ºC
The unit for Fahrenheit is degrees Fahrenheit (°F).
1 Fahrenheit degree = 5/9 of one Celsius degrees 1 Celsius degree = 1.8 Fahrenheit degree There is no constant ratio between the °F and °C numbers for the same temperature, because their zeros are at different temperatures. A Celsius number less than -40° is colder than the same Fahrenheit number. A Celsius number more than -40° is warmer than the same Fahrenheit number. And -40° is the same actual temperature in both °F and °C.
1 Celsius degree = 1.8 Fahrenheit degrees.1 Fahrenheit degree = 5/9 of one Celsius degree.

There are two reasons for this. The first is that a Fahrenheit degree is smaller than a Celsius degree. Four Celsius degrees is the same size as nine Fahrenheit degrees. The second reason is that 32 degrees Fahrenheit is zero degrees Celsius. If you put those two ideas together you figure out that -40°F = -40°C.
