Temperature conversions are an essential aspect of various scientific and engineering applications. Understanding the relationships between different temperature scales is crucial for accurate calculations and meaningful interpretations. This article focuses on converting degrees Kelvin to Rankine, providing a comprehensive guide for those working with temperature measurements.
The Kelvin and Rankine scales are two absolute temperature scales used in different contexts. The Kelvin scale, part of the International System of Units (SI), is widely used in scientific research and international applications. In contrast, the Rankine scale is primarily used in engineering and thermodynamic calculations, especially in the United States. Converting between these scales requires a simple yet precise formula, which will be explored in detail.
Understanding the Kelvin and Rankine Scales
The Kelvin scale is defined such that 0 K is absolute zero, and 1 K is equal to 1 degree Celsius. The Rankine scale, on the other hand, is related to the Fahrenheit scale, with 0°R being absolute zero and 1°R being equal to 1 degree Fahrenheit.
Conversion Formula
The conversion from Kelvin to Rankine is straightforward and can be achieved using the following formula:
°R = K × 1.8
Where °R is the temperature in Rankine and K is the temperature in Kelvin. This formula is derived from the relationship between the Kelvin and Celsius scales, and the Rankine and Fahrenheit scales.
| Kelvin (K) | Rankine (°R) |
|---|---|
| 0 | 0 |
| 100 | 180 |
| 273.15 | 491.67 |
| 373.15 | 671.67 |
