Celsius to Delisle (ºC to °De) formula
Delisle = (Celsius * 1.5) + -100
Celsius and Kelvin are two commonly used temperature scales in the field of science and everyday life. The Celsius scale, also known as the centigrade scale, is named after the Swedish astronomer Anders Celsius. It is based on the concept of dividing the range between the freezing and boiling points of water into 100 equal intervals. The freezing point of water is defined as 0 degrees Celsius, while the boiling point is defined as 100 degrees Celsius at standard atmospheric pressure.
The Celsius scale is commonly used in weather forecasts, household thermometers, and cooking, while the Kelvin scale is primarily used in scientific experiments, thermodynamics, and calculations involving gases.
The Delisle scale is a temperature scale that was developed by French astronomer Joseph-Nicolas Delisle in the early 18th century. It is named after him and is based on the Celsius scale, which is widely used today. The Delisle scale is a reverse scale, meaning that as the temperature increases, the Delisle value decreases.
On the Delisle scale, the boiling point of water is set at 0 degrees, while the freezing point is set at 150 degrees. This means that the Delisle scale has a larger range than the Celsius scale, with 180 degrees between the boiling and freezing points. To convert a temperature from Delisle to Celsius, you can use the formula: Celsius = (150 - Delisle) * 2/3.
While the Delisle scale was widely used in the 18th century, it has since fallen out of favor and is not commonly used today. The Celsius scale, on the other hand, is the most widely used temperature scale in the world, particularly in scientific and everyday applications. It is based on the freezing and boiling points of water, making it a practical and easily understandable scale for measuring temperature.
