Réaumur to Kelvin Converter

About Réaumur (°Ré) and Kelvin (K) Units

Réaumur (°Re) is a temperature scale named after the French scientist René Antoine Ferchault de Réaumur. In this scale, water freezes at 0°Re and boils at 80°Re. It was historically used in Europe for scientific work, brewing, and some industrial processes. Although it is largely replaced by Celsius today, Réaumur is still referenced in historical recipes, old scientific texts, and specialty brewing measurements. Kelvin (K) is the standard temperature unit used in science, physics, and engineering to measure absolute temperature. Unlike Celsius and Fahrenheit, Kelvin starts at absolute zero (0 K), which is the lowest possible temperature where all molecular motion stops. Kelvin does not use the degree symbol. For example, 0°C equals 273.15 K, and room temperature is about 298 K. It is widely used in laboratories, space science, thermodynamics, and any field that requires precise temperature measurements.
