Rankine to Celsius Converter

About Rankine (°R) and Celsius (°C) 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. Celsius (°C) is the most commonly used temperature unit in the world for everyday weather, cooking, and science measurements. In this scale, 0°C is the freezing point of water and 100°C is the boiling point. For example, normal body temperature is around 37°C, room temperature is about 20–25°C, and winter temperatures in many countries can drop below 0°C. Celsius is widely used because it is easy to understand and directly linked to the properties of water.
