Kelvin to Rankine Conversion | K to °R

Kelvin to Rankine Converter

A Kelvin to Rankine converter is a simple tool used to convert temperature values from the Kelvin scale to the Rankine scale. Both Kelvin and Rankine are absolute temperature scales, meaning they start at absolute zero. Because of this, converting between them is straightforward and commonly required in physics, engineering, and thermodynamics.

This guide explains how a Kelvin to Rankine conversion works, the formula used, examples, and when this conversion is needed.

Understanding Kelvin and Rankine

The Kelvin (K) scale is the standard temperature unit used in scientific research and the International System of Units (SI). It starts at absolute zero (0 K), the point where all molecular motion stops.

The Rankine (°R) scale is also an absolute temperature scale, but it uses Fahrenheit-sized degrees instead of Celsius-sized degrees. Rankine is primarily used in certain engineering and thermodynamics applications.

Because both scales begin at absolute zero, their relationship is linear and easy to calculate.

Kelvin to Rankine Formula

The standard Kelvin to Rankine formula is:

Rankine (°R) = Kelvin (K) × 9/5

This equation is used by every Kelvin to Rankine converter.

How to Convert Kelvin to Rankine

To manually convert Kelvin to Rankine, follow these steps:

1. Take the temperature value in Kelvin
2. Multiply it by 9/5 (or 1.8)
3. The result is the temperature in Rankine

Since both scales start at absolute zero, no addition or subtraction is required.

Kelvin to Rankine Conversion Examples

Here are a few examples showing how the conversion works:

• 1 K to Rankine
  1 × 9/5 = 1.8°R
• 100 K to Rankine
  100 × 9/5 = 180°R
• 273.15 K to Rankine
  273.15 × 9/5 = 491.67°R
• 300 K to Rankine
  300 × 9/5 = 540°R

These examples demonstrate how easy the Kelvin to Rankine conversion is.
