What is sub freezing temperature?

Sub freezing temperature refers to a temperature below the freezing point of water, which is 0 degrees Celsius (32 degrees Fahrenheit) or 273.15 Kelvin. At sub freezing temperature, water freezes and turns into ice. This temperature range is common in polar regions and during winter months in many regions.

Exposure to sub freezing temperatures can be dangerous to humans and animals if proper precautions are not taken. Hypothermia, frostbite, and other cold-related illnesses can occur if the body is exposed to sub freezing temperatures for extended periods of time. Proper clothing and shelter are necessary to protect against these risks.

Additionally, sub freezing temperatures can impact the functioning of equipment and machinery. Batteries, electronics, and engines may not work as efficiently in extreme cold temperatures. Ice and snow accumulation can also cause damage and create hazardous conditions for transportation on roads and runways.
