Rankine to Kelvin (ºR to K) formula
Kelvin = ((Rankine - 491.67) / 1.79999999) + 273.15
Converting from Rankine to Kelvin
Both Rankine and Kelvin are temperature scales used in scientific and engineering applications. While Rankine is primarily used in the United States, Kelvin is the standard unit of temperature in the International System of Units (SI).
To convert from Rankine to Kelvin, you need to subtract 491.67 from the given temperature in Rankine and then multiply the result by 5/9. Finally, add 273.15. This conversion factor accounts for the difference in the zero points of the two scales.
For example, let's say we have a temperature of 500 Rankine. To convert this to Kelvin, we subtract 491.67 from 500, which gives us 8.33. Then, we multiply 8.33 by 5/9, giving approximately 4.627. Finally add 273.15 to the value to get 277.77K.
Converting between Rankine and Kelvin is essential when working with temperature data in different systems. It allows for seamless communication and compatibility between different scientific disciplines and regions of the world.
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.
Kelvin, also known as the Kelvin scale, is a unit of measurement for temperature in the International System of Units (SI). It is named after the Scottish physicist William Thomson, 1st Baron Kelvin, who made significant contributions to the field of thermodynamics. The Kelvin scale is based on the absolute zero point, which is the lowest possible temperature where all molecular motion ceases.
Unlike most other temperature scales, Kelvin does not use degrees. Instead, it measures temperature in kelvins (K). The Kelvin scale is often used in scientific and engineering applications, particularly in fields like physics, chemistry, and meteorology. It is considered an absolute temperature scale because it starts from absolute zero, which is equivalent to -273.15 degrees Celsius or -459.67 degrees Fahrenheit.
One of the key advantages of the Kelvin scale is that it allows for precise and consistent measurements of temperature. It is particularly useful in scientific research and calculations involving gases, as it directly relates to the kinetic energy of molecules. Additionally, the Kelvin scale is used in many scientific formulas and equations, making it an essential tool for scientists and engineers worldwide.
