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.
About Rankine
Rankine is a unit of temperature measurement commonly used in engineering and thermodynamics. It is named after the Scottish engineer and physicist William John Macquorn Rankine, who made significant contributions to the field of thermodynamics in the 19th century. The Rankine scale is an absolute temperature scale, similar to the Kelvin scale, but with a different zero point.
The Rankine scale is based on the Fahrenheit scale, with the zero point set at absolute zero (-459.67°F). This means that the Rankine scale has the same size degree as the Fahrenheit scale, but starts at a different point. To convert between Rankine and Celsius, one must first convert from Celsius to Kelvin by adding 273.15, and then convert from Kelvin to Rankine by multiplying by 1.8. The formula for this conversion is: Rankine = (Celsius + 273.15) × 1.8.
While the Rankine scale is not commonly used in everyday life, it is widely used in engineering and thermodynamics, particularly in the United States. It is often used in calculations involving temperature differentials, such as in the study of heat transfer and energy systems. Understanding the Rankine scale and its conversion to Celsius is important for engineers and scientists working in these fields, as it allows for accurate and consistent temperature measurements and calculations.
