0 degrees Celsius is the freezing point of water, meaning that at this temperature, water changes from a liquid to a solid state, forming ice. This temperature is a key reference point in the Celsius scale, which is widely used around the world for measuring temperature. In addition to its significance in water's state change, 0 degrees Celsius is equivalent to 32 degrees Fahrenheit on the Fahrenheit scale. This temperature is commonly encountered in everyday weather reports, especially in regions that experience winter conditions, where temperatures can drop below freezing.
