Kelvin

Kelvin is a unit of temperature in the International System of Units (SI). It is named after the Scottish physicist William Thomson, 1st Baron Kelvin. The Kelvin scale is an absolute temperature scale, meaning that it starts at absolute zero, the theoretical point at which the motion of particles ceases. This makes the Kelvin scale particularly useful in scientific and engineering applications.

Converting Between Kelvin and Celsius

To convert from Celsius to Kelvin, you can use the following formula:

Kelvin = Celsius + 273.15

Conversely, to convert from Kelvin to Celsius, you can use the formula:

Celsius = Kelvin - 273.15
