About Delisle
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.
About Newton (temperature scale)
The Newton temperature scale, also known as the Newtonian scale, is a temperature scale that was proposed by Sir Isaac Newton in the 18th century. Unlike the Celsius or Fahrenheit scales, which are based on the properties of specific substances, the Newton scale is based on the rate of change of a physical property with temperature.
In the Newton scale, the zero point is defined as the temperature at which water freezes, similar to the Celsius scale. However, the scale is divided into 33 equal intervals, or degrees, between the freezing and boiling points of water. This means that each degree on the Newton scale is larger than a degree on the Celsius or Fahrenheit scales.
While the Newton scale was proposed by one of the most influential scientists in history, it did not gain widespread adoption and is not commonly used today. The Celsius and Fahrenheit scales, which are based on the properties of water and widely used in scientific and everyday applications, have become the standard temperature scales. However, the Newton scale remains an interesting historical curiosity and a testament to the ingenuity of Sir Isaac Newton.
