4 Kelvin is equivalent to -269.15 degrees Celsius. To convert Kelvin to Celsius, you need to subtract 273.15 from the Kelvin temperature. This is because the Kelvin scale starts from absolute zero, which is -273.15 degrees Celsius.

To understand the relationship between Kelvin and Celsius, it’s important to know that the Kelvin scale is an absolute temperature scale, while the Celsius scale is a relative temperature scale. In the Kelvin scale, 0 K represents absolute zero, the point at which all molecular motion ceases. On the other hand, 0 degrees Celsius represents the freezing point of water at standard atmospheric pressure.

For example, if you have a temperature of 300 Kelvin, you can convert it to Celsius using the formula:

Celsius = Kelvin – 273.15

Celsius = 300 K – 273.15

Celsius ≈ 26.85 degrees Celsius

This conversion is important in many scientific fields, such as physics, chemistry, and engineering, where precise temperature measurements are necessary. For instance, in physics, the Kelvin scale is often used in thermodynamics and the study of gases, while in chemistry, Kelvin is often utilized in the study of reactions at specific temperatures.

In conclusion, 4 Kelvin is equal to -269.15 degrees Celsius, and the conversion between the two temperature scales is essential in various scientific disciplines. Understanding this conversion allows for accurate temperature measurements and calculations, ensuring the reliability of scientific data.
