Delisle to Celsius: Definition, History, Historical Uses, and Examples
Definition
Delisle (°De) is a historical temperature scale where 0°De = boiling point of water and 150°De = freezing point of water at 1 atm. Celsius (°C) is the metric temperature scale where 0°C = freezing and 100°C = boiling point of water. The conversion formula is: °C = 100 - (°De × 2/3).
Origin or History
The Delisle scale was proposed by French astronomer Joseph-Nicolas Delisle in 1732. It was designed as an inverted scale where higher numbers represented colder temperatures, which was intuitive for Russian winters where the scale was most commonly used. The scale was widely used in Russia until the 19th century.
Historical Use
- Russian Empire: Official temperature scale used throughout Russia and its territories.
- Scientific Research: Temperature measurements in astronomy and meteorology.
- Weather Recording: Historical weather data and climate studies.
- Industrial Processes: Temperature control in manufacturing and mining.
- European Science: Scientific experiments and temperature measurements.
