Rankine Scale: Unveiling the 491.67°R Difference

The Rankine scale, named after physicist William John Macquorn Rankine, is an absolute temperature scale with its zero point set at absolute zero, the temperature at which molecular motion ceases. Its numerical values are obtained by adding 459.67 to the temperature in degrees Fahrenheit.

Why the Rankine Scale?

The Rankine scale is widely used in engineering and science due to its absolute nature and its linear relationship with other absolute scales, such as the Kelvin scale. This linearity simplifies calculations involving temperature differences and makes it convenient for use in thermodynamics and heat transfer applications.

Pain Points:
