Celsius to Kelvin
To convert Celsius into Kelvin, the formula is K=C+273.15. C stands for Celsius and K for Kelvin. The 273.15 is used because absolute zero in Kelvin is equal to 273.15 degrees below the freezing in Celsius.
An Example
Choose the degrees you want to change. Suppose you want to change 30 degrees Celsius. The formula would then be K=30+273.15. Now you just have to perform some mathematical calculations. In this example, 30+273.15=303.15. That is the Kelvin equivalent of the Celsius scale.
Calculating by Hand
Remember that an increment of K is the same as an increment of C. That is why 0 K is equivalent to -273.15 C. 1 K = -272.15 C, K = -271.15 C and so on. To change 3 K to C, the proceeding formula may be used: Celsius = [K] -273.15 Celsius = [3]-273.15 Celsius = 3-273.15 Celsius = -270.15.
Using Computer Software
You can use computer programs to change Celsius into Kelvin and vice versa. To make the conversion using Microsoft Excel, utilize this formula: Cell A1=”K”Cell B1=”C”Cell A2= Kelvin MeasurementCell B2=CONVERT(A2,A1,B1)
Add 273.15
However, the simplest method for many is just adding 273.15. To convert 99.9 C (the point when water boils) the following equation is used: [K] = Celsius + 273.15[K] = [99.98] + 273.15[K] = 373.13.
Facts about the Kelvin Temperature Scale
It is the standard used by the Standard International (SI) units for science. Majority of scientific examinations are conducted in Kelvin. The Kelvin temperature scale is preferred by scientists because they are set on gas properties. This makes them more accurate than Celsius.
Unlike common everyday applications, scientific studies and examinations require the most accurate temperature scale possible. While Celsius can also be used for some scientific calculation, it is more limited because the basis is boiling and freezing points of water.
The Kelvin on the other hand, measures heat energy. O K or -273.15 C is the state in which no energy can be found in a substance. For this reason it is known as the absolute zero.
The idea of the Kelvin came from the scientist William Thomson around the 19th century. The idea evolved from his need to gauge absolute zero temperatures, something that could not be done with the scales at the time.
It doesn’t take a lot of skills to convert Celsius into Kelvin and vice versa. Although the Kelvin isn’t used much in everyday applications, it is still something that bears knowing.
