Celsius to Delisle Converter

About Celsius (°C) and Delisle (°D) Units

Celsius (°C) is the most commonly used temperature unit in the world for everyday weather, cooking, and science measurements. In this scale, 0°C is the freezing point of water and 100°C is the boiling point. For example, normal body temperature is around 37°C, room temperature is about 20–25°C, and winter temperatures in many countries can drop below 0°C. Celsius is widely used because it is easy to understand and directly linked to the properties of water. The Delisle scale (°De), created in 1732 by French astronomer Joseph-Nicolas Delisle, is a historical temperature system. Unlike modern scales, it sets the boiling point of water at 0°De and the freezing point at 150°De. This scale was mainly used in Russia and parts of Europe for early meteorological observations and scientific measurements. Although no longer used today, Delisle remains of interest for historical studies and temperature conversions.
