## Rankine (R)

Rankine is an absolute temperature scale primarily used in engineering and thermodynamics. It is similar to the Fahrenheit scale, but it starts from absolute zero. In the Rankine scale, absolute zero is 0 R, and the size of one degree Rankine is equal to the size of one degree Fahrenheit. Therefore, the Rankine scale has the same increments as the Fahrenheit scale but starts from absolute zero.

## Kelvin (K)

Kelvin is also an absolute temperature scale and is the primary unit of temperature measurement in the scientific community. It is based on the properties of gases and starts from absolute zero as well. In the Kelvin scale, absolute zero is 0 K, and the size of one Kelvin is the same as one degree Celsius. Therefore, the Kelvin scale has the same increments as the Celsius scale but starts from absolute zero.

## How to convert Rankine to Kelvin

To convert from Rankine (R) to Kelvin (K), you can use the following formula:

K = R × 5/9

In this formula, you simply multiply the temperature in Rankine by 5/9 to obtain the equivalent temperature in Kelvin. The Kelvin scale is an absolute temperature scale, similar to Rankine, so the conversion between them is a straightforward ratio.

For Example- Convert 650 Rankin to Kelvin

Ans. K = R × 5/9

= 650 x 5/9

= 3250 / 9

= 361.1

## Frequently Asked Questions on Rankine to Kelvin

### What is the formula for Rankine to Kelvin?

The formula for converting Rankine (R) to Kelvin (K) is: K = R × (5/9)

### What is 650 R to K?

To convert 650 R to K, we can use the conversion formula: K = 650 × (5/9) ≈ 361.111 K

### What is the unit of Rankine?

The unit of Rankine is denoted by R. It is named after the Scottish engineer and physicist, William Rankine, who proposed the absolute temperature scale.

### What is the difference between Rankine and Kelvin?

The main difference between Rankine and Kelvin is the reference point for absolute zero. In the Kelvin scale, absolute zero is 0 K, which is the lowest possible temperature. On the Rankine scale, absolute zero is 0 R. The size of one degree Rankine is equal to one degree Fahrenheit, whereas the size of one degree Kelvin is equal to one degree Celsius. Kelvin is used in the scientific community and in most countries, while Rankine is primarily used in engineering and thermodynamics in the United States.

### What is the symbol for Rankine?

The symbol for Rankine is R. It is written after the numerical value to denote temperature in Rankine. For example, 100 R represents 100 Rankine.

### What is the use of Rankine formula?

The Rankine scale and its associated formula are primarily used in engineering and thermodynamics for temperature measurements and calculations. It is often used in fields such as mechanical engineering, aerospace engineering, and energy systems. The Rankine formula is useful for converting temperatures between Rankine and other temperature scales, performing thermodynamic calculations, and analyzing heat transfer processes.
