Rankine to Kelvin Converter

About Rankine (°R) and Kelvin (K) Units

Rankine (°R) is a temperature scale named after the Scottish engineer William Rankine. It is mainly used in engineering and thermodynamics, especially in the United States. The Rankine scale uses absolute zero as its starting point, so 0°R equals absolute zero, and water freezes at 491.67°R. It is commonly used in heat engine calculations, thermodynamic cycles, and aerospace engineering where absolute temperatures are required in Fahrenheit increments. 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.
