Understanding Reaumur and Kelvin

Reaumur (°Re): The Reaumur scale was developed in the 18th century by René Antoine Ferchault de Réaumur.
On this scale:
Water freezes at 0°Re
Water boils at 80°Re
The Réaumur scale was widely used in Europe for science and daily life before being replaced by Celsius. Today, it still has relevance in food processing industries (such as cheese-making, brewing, and syrup production) and in historical scientific research.

Kelvin (K): Kelvin is the SI base unit of temperature, used worldwide in science, engineering, astronomy, and thermodynamics.
On this scale:
Absolute zero is 0 K (the lowest possible temperature in nature).
Water freezes at 273.15 K
Water boils at 373.15 K
Kelvin is the most important unit in modern physics, chemistry, and engineering applications.

👉 Conversion Value: The Reaumur to Kelvin conversion requires converting Reaumur first into Celsius and then shifting it into Kelvin.

Formula to Convert Reaumur to Kelvin

K = (°Re × 5/4) + 273.15

Examples of Conversion

Convert 0°Re to Kelvin

(0 × 5/4) + 273.15 = 273.15 K

✅ So, 0°Re = 273.15 K (freezing point of water).

Convert 20°Re to Kelvin

(20 × 5/4) + 273.15 = 298.15 K

✅ So, 20°Re = 298.15 K (room temperature).

Convert 37°Re to Kelvin

(37 × 5/4) + 273.15 = 319.40 K

✅ So, 37°Re = 319.40 K (a hot summer day).

Convert 80°Re to Kelvin

(80 × 5/4) + 273.15 = 373.15 K

✅ So, 80°Re = 373.15 K (boiling point of water).

Convert -15°Re to Kelvin

(-15 × 5/4) + 273.15 = 254.40 K

✅ So, -15°Re = 254.40 K (below freezing, common in winter conditions).
