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 Celsius (°C) is a unit of temperature measurement in the metric system. It is used to quantify temperature based on the freezing point of water at 0°C and the boiling point at 100°C under standard atmospheric conditions. Celsius is widely used around the world for everyday temperature readings, weather forecasts, and scientific research. This scale is integral to the International System of Units (SI) and is commonly used in most countries, excluding the United States, where Fahrenheit is more prevalent.
To convert a temperature from Rankine (°R) to Celsius (°C), we use the formula:
Celsius = (Rankine − 491.67) × 5/9
Let's go through the conversion step by step for 20°R:
Therefore, 20 Rankine is equivalent to -262.0388888888889 degrees Celsius.
