### Celsius to Kelvin conversion

Temperature impacts almost every natural activity, thus it is critical for anybody studying chemistry, physics, or biology to know how to convert degrees Celsius to degrees Kelvin. There is just one difference between the two scales, and that is the placement of the zero. It is much easier to grasp and, more importantly, remember if you know where the two scales come from and how they are used.

**Temperature is measured using the Celsius system (degrees Celsius)**

The Celsius temperature scale was developed in 1742 by Anders Celsius, a Swedish astronomer. This scale is based on the temperature of water at sea level, where the boiling and freezing temperatures are. Due to the fact that the freezing point of water is the reference point for determining temperature, and the boiling point is the reference point for determining temperature, the temperature scale was initially referred to as a centigrade scale, a name that is still widely used today.

Using the Celsius scale, you may compare two points in temperature. A thermometer can only tell you how much higher or lower your internal temperature is when compared to a reference temperature, such as that at which water freezes or melts. The “size” of the degree centigrade is defined by dividing the second reference temperature by the first.

**It is necessary to make use of both the Kelvin and the absolute temperature scales (K)**

A temperature scale that does not depend on a reference point, such as the Celsius or Centigrade scales, is known as the Kelvin scale. There is no thermal energy present at the zero point on the Kelvin scale. To put it another way, the Kelvin scale’s zero point reflects the temperature at which nothing lower exists; there can be no lower temperature. The Kelvin scale was created in 1848 by William Thompson (better known by his peerage as Lord Kelvin), who gave each unit on his scale the same size as the degree on the Celsius scale. Conversion from **Celsius to Kelvin** is easier since the only difference between these two systems is where absolute zero lies, which corresponds to -273.15 °C on the Celsius scale.

There is no such thing as a Kelvin “degree” or a symbol for degree (°) for the unit of temperature on the Kelvin scale; it is simply called Kelvin and carries the sign K. This is the situation because the scale is on an absolute rather than a relative scale. So, for example, the number 273 Kelvin is written as 273 Kelvin, not 273 “degrees” Kelvin as some people would think.

**The formula for converting Celsius to Kelvin is shown below in a more precise manner**

The preceding formula, despite its simplicity, often leads to misunderstandings due to the omission of units until the very end. In order to avoid this, a better version of the same equation should be used. Many textbooks use the symbol T to represent absolute temperature, but the letter G to represent relative temperature in degrees Celsius (theta, which is the t of the Greek alphabet).

**Here are some tips for converting degrees Celsius to degrees Kelvin**

The output of a unit conversion of **c to kelvin **must be checked to make sure it is correct. As simple as this method is, even the most seasoned engineer may make mistakes. The first conversion must be multiplied by 273.15 in order to equal the second, and vice versa, and it is easy to make an error if you do the two conversions back-to-back. The following two tips should be followed to ensure that the conversion is always done correctly:

Both the temperature in Kelvin and the temperature in degrees Celsius must be greater for them to be greater. Since a temperature in Kelvin can never be lower than a temperature in Celsius, the outcome of converting 400 degrees **c to k **will always equal 127 degrees Celsius.

Temperature in Kelvin can never be negative since it is an absolute scale and the lowest value is zero (no units, just zero). It is improper to convert a temperature to Kelvin (K) if the result is -150 K.

**Summary title: Change the unit of measurement from Celsius to Kelvin **

**Summary: **

Any temperature may be converted to any other temperature scale, whether relative or absolute, if you know the temperature in degrees Celsius. Among other things, translating Celsius to Fahrenheit or **Celsius to Kelvin **is an example of working with a relative scale (which is an absolute scale).
