The 0 °C isotherm under normal conditions. The freezing level, or 0 °C (zero-degree) isotherm, represents the altitude in which the temperature is at 0 °C (the freezing point of water) in a free atmosphere (i.e. allowing reflection of the sun by snow, icing conditions, etc.).
The theoretical temperature is determined by extrapolating the ideal gas law; by international agreement, absolute zero is taken as 0 kelvin (International System of Units), which is −273.15 degrees on the Celsius scale, [1] [2] and equals −459.67 degrees on the Fahrenheit scale (United States customary units or imperial units).

In the southern part of Finland, -15 °C (5 °F) is considered the limit of severe frost. The thermometer in the picture shows -17 °C (1.4 °F). The English word "frost" has 2 base meanings that are related to each other but nevertheless sufficiently different: temperature of air below the freezing point of water (ca 273 K)
The zero-curtain effect occurs in cold (particularly periglacial) environments where the phase transition of water to ice is slowed due to latent heat release. The effect is notably found in arctic and alpine permafrost sediments, and occurs where the air temperature falls below 0 ° C (the freezing point of water) followed by a rapid drop in ...
Working in temperatures of minus 15 degrees (minus 26 degrees Celsius), Villegas said the best way to feel warm was to “just keep moving.” ... chills as low as 30 degrees below zero (minus 34 ...
Changing the temperature by 7 to 10 degrees for eight hours a day, in winter and summer, can save about 10% a year on heating and cooling, the department said. This step to save money and energy ...
The temperature in portions of the Yakutia region of eastern Russia, where Yakutsk is located, dropped below 40 degrees below zero Fahrenheit (40 degrees below zero Celsius) during the middle of ...
Negative temperatures can only exist in a system where there are a limited number of energy states (see below). As the temperature is increased on such a system, particles move into higher and higher energy states, so that the number of particles in the lower energy states and in the higher energy states approaches equality.
