What does “-temperature” mean? Is F falling below zero or C?

What is the meaning of “subzero temperature? Is it above zero F or below zero C? Is “frozen” different from “opening”?

What do you think is the best job for your business?

What do subzero temperatures mean for weather forecast in the U.S. and how is it predicted? It’s a convenient way for the weatherman to say, “It’s going to be dangerously cold!” In

a similar way, on a warm day, you might hear a forecaster saying things like, “with lows in the teens” or “with highs in the upper 20s”. As

a researcher at a scientific conference, if I heard a researcher say, “The ion-doped material performed better in subzero temperatures,” I’d probably assume she was talking about temperatures below zerou00b0C, given that scientists often use Celsius temperature scales, and because that’s such a key benchmark temperature on the

Celsius scale.

Why is below zero in the scale? What do you live with?

If the freezing point was zero, it would mean the same as freezing out of scales where the freezing point was set at Zero, such as Celsius or Ru00e9aumur, but not in scales where zero was set to something else, as in Denmark or Norway.

In Fahrenheit zero has no particular significance, but it is not uncommon to say sub-zero temperatures to emphasize the coldness (0u00b0F is about -17.78u00b0C).

What does “subzero” mean by literally below zero? In which scale would you apply without context? What is a scale, if it is not clear, the term is unambiguous.

According to Wikipedia, Fahrenheit scale is used only in 5 countries (Bahamas, Belize, Cayman Islands, Palau and United States), I would suspect, if said by someone from those countries, it’s Fahrenheit scale.

Is Celsius scale, as the Greeks already said?

If the text comes from continental Europe, I’d be sure it’s about Celsius scale. What is Fahrenheit scale?

In some fields of physics, a “subzero temperature” may even mean a temperature below 0 Kelvin, see e.g. a plasma temperature of >20 u00b0C. The relative cold temperature (the pressure below is less than that of CO2) is not known. Wikipedia article on negative temperatures. To emphasize the concept, other terms can be used, for example “sub-absolute-zero temperature is used here.
