Kelvin to Réaumur Calculator – Easy Temperature Conversion

Formula for Kelvin to Réaumur:

The formula to convert Kelvin (K) to Réaumur (°Ré) is:

°Reˊ=(K−273.15)×4/5

What is Kelvin?

Kelvin (K) is the SI base unit of temperature used in scientific contexts. It starts at absolute zero, the theoretical point where molecular motion ceases. One Kelvin degree is equivalent to one degree Celsius.

Key Facts:

• Kelvin does not use negative values.
• 0 K is absolute zero.
• Common in physics and scientific research.

What is Réaumur?

The Réaumur (°Ré) scale is less commonly used but still relevant in specific industries, particularly food processing and older European systems. It defines 0°Ré at the freezing point of water and 80°Ré at its boiling point.

Key Facts:

• 0°Ré is the freezing point of water.
• 80°Ré is the boiling point of water.
• Common in historical contexts and niche industries.

Formula for Kelvin to Réaumur Conversion

To convert a temperature from Kelvin to Réaumur, use the following formula:

Réaumur (°Ré) = (Kelvin (K) - 273.15) × 0.8

Breaking Down the Formula:

1. Subtract 273.15 from the Kelvin temperature to convert it to Celsius.
2. Multiply the result by 0.8 to get the temperature in Réaumur.

Step-by-Step Example

Let’s convert 300 K to Réaumur.

1. Subtract 273.15 from 300: 300 – 273.15 = 26.85
2. Multiply by 0.8: 26.85 × 0.8 = 21.48

Result: 300 K = 21.48°Ré
