To convert 80 Kelvin to Celsius, you can use the formula: Celsius = Kelvin – 273.15. This is because the Kelvin scale starts at absolute zero, which is equivalent to -273.15 degrees Celsius. Therefore, to convert from Kelvin to Celsius, you simply subtract 273.15 from the given temperature in Kelvin.

So, if we apply this formula to 80 Kelvin, we get:

Celsius = 80 – 273.15

Celsius = -193.15 degrees

So, 80 Kelvin is equivalent to -193.15 degrees Celsius.

It’s important to note that the Kelvin scale is often used in scientific and engineering contexts, especially when dealing with extremely low temperatures, because it starts at absolute zero and has the same size units as the Celsius scale. This makes it easier to work with in calculations. For example, when studying cryogenics, which deals with the production and behavior of materials at very low temperatures, the Kelvin scale is commonly used.

In summary, to convert Kelvin to Celsius, you simply subtract 273.15 from the given temperature in Kelvin using the formula Celsius = Kelvin – 273.15. This conversion allows for a better understanding of temperature in scientific applications, particularly when dealing with extremely low temperatures.
