What does it mean when the temperature is above 0 below 0?
It means below zero on whichever scale is in use or generally understood— centigrade, Delisle, or what have you. It would mean the same as freezing in scales where the freezing point of water is set at zero, such as Celsius or Réaumur, but not in scales where zero is set to something else, as in Leiden or Rømer.
What does below 0 degrees mean?
Fahrenheit sets zero to the freezing point of a concentrated salt water solution, and 100 to a nominal body temperature. For both Fahrenheit and Celsius, 10 below zero indicates 10 degrees below the zero point or -10 on the scale. -10°F is the same as (roughly) -23°C, and -10°C is the same (roughly) as +14°F.
Is 20 degrees Fahrenheit below zero?
Temperatures below 0 are negative. J20°F is 20 degrees below 0°F. J30°C is 30 degrees below 0°C. 30°C is 30 degrees above 0°C.
What is 20 degrees below Fahrenheit in Celsius?

How cold is subzero?
Sub-zero temperatures are below 0° centigrade or, in the United States, below 0° Fahrenheit.
How cold is 20 below?
Below 20 is cool, below 10 degrees is cold, and below zero degrees means that it will be icy outside as the water will freeze and it will feel very cold outside.
Is 21 degrees Fahrenheit below freezing?
F. It’s twenty-one degrees below zero. If you say “degrees”, you have to say “zero”. Of course, twenty-one below would be said in the context of talking about temperatures so the meaning was clear.
Is zero degrees Celsius freezing?
Celsius is a relative scale. The temperature at which water freezes is defined as 0 °C.
What does 10 below zero mean in Celsius?
In Celsius, zero is the temperature at which pure water freezes, and 100 is where it boils. Fahrenheit sets zero to the freezing point of a concentrated salt water solution, and 100 to a nominal body temperature. For both Fahrenheit and Celsius, 10 below zero indicates 10 degrees below the zero point or -10 on the scale.
What does zero mean on the Fahrenheit scale?
I came across your column on what zero means on the Fahrenheit scale. You blew it. You said that, unlike 32 or 212 degrees, zero degrees corresponded to nothing in nature—it was merely an arbitrarily assigned number. It isn’t. It’s the temperature at which seawater will freeze.
What is the meaning of 100 degrees Celsius?
In Celsius, zero is the temperature at which pure water freezes, and 100 is wh It means cold. But that’s probably not what you’re asking… It depends on the temperature scale you are using.
How did they come up with the zero temperature?
There you have it. Fahrenheit, following Roemer, simply determined the distance between the marks for the freezing point of water and body heat on his glass thermometers (64 degrees, in the scale he would ultimately develop), measured off half this distance (32 degrees) below the freezing point, and called that zero.
