Understanding the Rankine Scale: Definition, Differences with Celsius, and Conversion Formulas

Rankine is a unit of measurement for power, named after William Rankine, a Scottish engineer who first proposed it in 1859. It is defined as the rate at which work is done or energy is transferred, and it is typically measured in watts (W). The rankine is used in the field of thermodynamics to describe the power output of a heat engine or the power input to a heating or cooling system.

2. What is the difference between Rankine and Celsius scale ?

The Rankine scale is a temperature scale that is based on the absolute zero point, which is the lowest possible temperature. It is used in the field of thermodynamics to describe temperatures above absolute zero. The Celsius scale, on the other hand, is a temperature scale that is based on the freezing and boiling points of water. It is commonly used in everyday applications, such as measuring the temperature of the air or the temperature of a liquid.

3. What is the formula for converting Rankine to Celsius ?

To convert from Rankine to Celsius, we can use the following formula:

Celsius = (Rankine - 491.67) / 100

This formula assumes that the temperature is measured in Rankine and we want to convert it to Celsius. The constant 491.67 is the difference between the absolute zero point (in Rankine) and the freezing point of water (in Celsius).

4. What is the formula for converting Celsius to Rankine ?

To convert from Celsius to Rankine, we can use the following formula:

Rankine = Celsius + 491.67

This formula assumes that the temperature is measured in Celsius and we want to convert it to Rankine. The constant 491.67 is the difference between the freezing point of water (in Celsius) and the absolute zero point (in Rankine).
