47 deg F
-40 is the only temperature where F and C are exactly the same. Neither one is colder.

No F = 9/5 C + 32 = 1.8(20) + 32 = 68F which is warmer than 40F
-30° C = -54 + 32 = -22° F = 8° F warmer than -30° F.-30° F = -34.4° C = 4.4° C colder than -30° C.-30° C is warmer than -30° F.Above -40, °C is warmer than °F.Below -40, °C is colder than °F.
Neither. -40 °C is equal to -40 °F.
No, -8 F is six degrees colder than -2 F.
40F is colder because it is only 8F above freezing point of water and 40C is warmer because it is it is about 3C higher than the human body temperature. 40F = (40 - 32) x 5/9 = 4.4444 degrees C 40C = (40 x 9/5) + 32 = 104 degrees F
No, -80 F is 10 degrees colder than -70 F because it is farther below zero.
Yes, 20C is colder than 78F. 20C is 68F.
If C is Celsius temperature and F is the Fahrenheit temperature, the relation between them is: F=(9/5)C+32 You can graph that into a linear function. And since the line y=x (this is when y is Celsius) and y=(9/5)x+32 (this is when y is Fahrenheit) have different slopes, they are going to meet once on the graph. (Different slopes mean they are not parallel and only parallel lines don't meet each other in a 2D. And the point they meet is the point where C and F are equal. And if the temperature is hotter than that, F>C, and if the temperature is colder than that, C>F) x=(9/5)x+32 So x=-40 (C=-40, F=-40) Therefore if it's hotter than -40°C (or -40°F), Fahrenheit is bigger than Celsius (when it's the same amount of heat). And if it's colder than -40°C (or -40°F), Celsius is bigger than Fahrenheit (when it's the same amount of heat)
It is not! Below -40 degrees (where C and F are the same), x deg Celsius is colder than x deg F, while above -40 deg Celsius is hotter. Just because you are used to temperatures above -40 degrees does not mean that what happens below that temperature can be ignored.
