What is colder minus 40 degrees centigrade or 40 degrees Fahrenheit?

Answer 1

That depends on which degrees you mean.

Degrees are measurements of atomic movement is substances. 0 degrees is a signifier for a certain amount of movement in your given substance. If you wanted the substance to be hotter than the amount of movement would have to increase. This goes the same for making a substance colder.

Half of 0 degrees is half the atomic movement in your substance. You will need to specify Celsius, Fahrenheit, kelvin etc. to get a numerical answer.

Also, as something to think about, are you measuring the temperature (and therefore the atomic movement) of a large mass, or a small one? For a large mass could have more movement overall but still be the same temperature as a smaller one with less.

example: if we have an iceberg and a ice cube that are the same temperature, the iceberg has more movement. Therefore more heat than the ice cube but the temperature are still the same.

Answer 2

The zero points on both the Fahrenheit and Celsius scales are arbitrary and so these are interval scales, not ratio scales. As a result, there is no meaning to twice as cold or three times as hot.

Answer 3

-40 C is colder than 40 F.

-40 C and -40 F are the same temperature.

Answer 4

minus 40 degrees centigrade is colder by 800F
