Freezing temperature is the temperature at which water freezes and turns into ice. It is usually measured at the height of 1.2 meters above the ground surface and is 0°C, 32°F, or 273 K. A "freeze" is anytime the temperature drops below 32°F, while a "frost" is technically the ice crystals that form when moisture in the air is converted to ice without first becoming dew. A frost occurs when the air temperature drops between 36 and 32°F.

It is important to note that there are different degrees of frost severity, ranging from "slight" to "very severe," depending on the location and usual temperatures occurring in winter. When temperatures reach 32°F or lower, it is considered freezing, and the process of solidification of water and the formation of ice in aqueous solutions occurs.

In summary, freezing temperature is the temperature at which water freezes and turns into ice, and it is 0°C, 32°F, or 273 K. A freeze occurs when the temperature drops below 32°F, while a frost occurs when the air temperature drops between 36 and 32°F.
