Temperature Unit Converter

Temperature is a fundamental quantity in thermodynamic systems and is expressed using different units depending on the application. On this page, you can perform conversions between commonly used temperature units such as Celsius (°C), Kelvin (K), Fahrenheit (°F), and Rankine (R), and view their definitions, formulas, and example applications.

Dimension: [temperature]     SI Base Unit: Kelvin {K}

Other Common Units: °C, °F, R

In scientific studies, especially in thermodynamic analyses, the use of Kelvin is widespread.

In everyday life, the °C and °F units are commonly used.

In engineering and industrial applications, temperature conversions are critical for process design, control systems, and data comparison.

The Rankine scale is mainly used in certain American engineering systems.
