Provide the value below in R:
The Rankine (°R) scale is an absolute temperature scale used primarily in thermodynamics and engineering in the United States. It is similar to the Kelvin scale but uses Fahrenheit degrees for increments. The Rankine scale starts at absolute zero, just like Kelvin, but with 1 Rankine degree being equivalent to 1 Fahrenheit degree. It is used to analyze thermodynamic processes in systems where temperature measurements are relative to absolute zero, often in the context of heat engines and refrigeration.
A degree Fahrenheit (°F) is a unit of temperature measurement primarily used in the United States and its territories. It is based on a scale where the freezing point of water is 32°F and the boiling point is 212°F, under standard atmospheric conditions. The Fahrenheit scale is often used in weather reports, cooking, and heating systems in the U.S. It provides a finer resolution for temperature differences within the commonly encountered range of everyday life compared to the Celsius scale.
To convert a temperature from Rankine (°R) to Fahrenheit (°F), we use the formula:
Fahrenheit = Rankine − 459.67
Let's go through the conversion step by step for 20°R:
Therefore, 20 Rankine is equivalent to -439.67 degrees Fahrenheit.
