How to Convert 120°F to °R (Rankine Temperature Scale)

The Rankine temperature scale (°R) is an absolute temperature scale that is based on the Fahrenheit scale (°F). The Rankine scale is named after the Scottish physicist and engineer William John Macquorn Rankine, who proposed the scale in 1859.

The Rankine scale is defined by the following equation:

°R = °F + 459.67

This equation means that the Rankine temperature of a substance is equal to the Fahrenheit temperature of the substance plus 459.67.

Why Convert from Fahrenheit to Rankine?

The Rankine temperature scale is used in a variety of scientific and engineering applications. Some of the benefits of using the Rankine scale include:

• The Rankine scale is an absolute temperature scale, which means that it has a true zero point. This makes the Rankine scale more useful for scientific calculations than the Fahrenheit scale, which does not have a true zero point.
• The Rankine scale is a linear scale, which means that the difference between two Rankine temperatures is always equal to the difference between the corresponding Fahrenheit temperatures. This makes the Rankine scale easier to use for calculations than the Fahrenheit scale, which is a non-linear scale.

Step-by-Step Instructions for Converting from Fahrenheit to Rankine

To convert a Fahrenheit temperature to a Rankine temperature, follow these steps:

1. Add 459.67 to the Fahrenheit temperature.
2. The resulting number is the Rankine temperature.

For example, to convert 120°F to °R, follow these steps:

1. Add 459.67 to 120°F: 120°F + 459.67 = 580.67°R
2. The Rankine temperature is 580.67°R.
