The **Kelvin scale****(°K**) is the basic unit of thermodynamic temperature and is used in physics and chemistry in particular. **1 °K corresponds to -272.15 °C or -457.87 °F.** Converted, this means: **273.15 K = 0 °C**.

While many people are familiar with the Celsius and Fahrenheit scales, it is useful to know how to convert between Kelvin and these other units.

## Kelvin to Celsius

The Celsius scale (°C) is probably the best known and most widely used temperature scale in the world, especially in scientific contexts. The conversion from Kelvin to Celsius is simple: **°C = K - 273.15**

This means that if you subtract 273.15 from a Kelvin temperature, you get the value in Celsius.

Example: **273.15 K = 0°C**

## Kelvin in Fahrenheit

In countries such as the USA, the Fahrenheit scale (°F) is more commonly used. The conversion from Kelvin to Fahrenheit requires a few extra steps: **°F = (K - 273.15) x ((9/5) 32)**

Example: 0 K (absolute zero) = **-459.67°F**

## Kelvin in Rankine

The Rankine scale (°R) is mainly used in the engineering sciences, especially in the USA. The conversion from Kelvin to Rankine is directly proportional: **°R = K x (9/5)**

Example: 1 K = 1.8 °R

## Practical applications and significance

The Kelvin scale is particularly important in science, as it has absolute zero as its starting point. At 0 Kelvin, molecular movement stops and there is no heat energy. This differs from the Celsius and Fahrenheit scales, where 0 merely represents a fixed point, but not absolute zero.

Understanding the conversion between these scales is important to correctly interpret and apply data, especially in scientific and technical fields.

In conclusion, understanding the different temperature units and their conversions is important for many disciplines. Using the formulas above, you can easily switch between Kelvin, Celsius, Fahrenheit and Rankine.
