Best Answer

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.

At -40 degrees.

34.5 degrees Celsius is the same as 94.1 degrees Fahrenheit. 34.5 degrees Fahrenheit is the same as 1.4 degrees Celsius.

The Celsius scale has its 'zero' at the same temperature as 32 on the Fahrenheit scale, and each Celsius degree is the same size as 1.8 Fahrenheit degrees.

-10 degrees Celsius is the same temperature as 14 degrees Fahrenheit.

A degree Celsius, although it has the same name, is equal to 1.8 degrees on the Fahrenheit scale. You can see that for the freezing and boiling points of water, there are 100 Celsius degrees (100-0) between the two temperatures, while there are 180 (212-32) of the smaller fahrenheit degrees.

The answer is: -40. 40 degrees below zero is the same in Celsius and Fahrenheit. (233.15 kelvin)

-10 degrees Celsius is the same temperature as 14 degrees Fahrenheit.

Temperatures in that range are associated with stellar fusion, and are usually expressed in Kelvin, which is practically the same as Celsius for those high temperatures. However, 15 million °C would equal 27 million °F. Fahrenheit is almost never used for such high temperatures. Celsius and Kelvin are normally used. But 15 million degrees on the Celsius scale would be approximately 27 million degrees on the Fahrenheit scale.

12 degrees Celsius is the same as 53.6 degrees Fahrenheit. Therefore, 12 Celsius is colder than 56 degrees Fahrenheit.
