WebThe 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, … Web23 Oct 2024 · In 1742, Swedish astronomer Anders Celsius developed a thermometer scale by dividing the freezing and boiling points of water into 100 degrees. Celsius chose 100 °C as the freezing point of water, and 0 °C degrees as the boiling point of pure water at sea level air pressure.
