The Kelvin measurement scale is a thermodynamic scale where zero indicates the point at which the molecules do not emit heat and are completely immobile. To be able to convert a measurement expressed in Kelvin to one expressed in Fahrenheit or Celsius, you can use the steps shown in this guide.
Steps
Method 1 of 2: Convert Kelvins to Degrees Fahrenheit
Step 1. Write the formula to convert Kelvin to Fahrenheit: ºF = 1.8 x (K - 273) + 32.
Step 2. Note the temperature in Kelvin
For example 373 K. Remember that in the case of a measurement of a temperature expressed in Kelvin, the word 'degrees' is omitted.
Step 3. Subtract the value '273' from the temperature in Kelvin
In our example we will get 373 - 273 = 100.
Step 4. Multiply the result by 9/5 or 1.8
The answer to your problem will then be the following 100 * 1.8 = 180.
Step 5. Now you just have to add 32 to the final result, getting 180 + 32 = 212
So 373 K corresponds to 212 ºF.
Method 2 of 2: Convert Kelvins to Degrees Celsius
Step 1. Write the formula for converting Kelvin to degrees Celsius: ºC = K - 273.
Step 2. Note the temperature in Kelvin
In our example we consider the value 273 K.
Step 3. Following the given formula, subtract 273 from the temperature expressed in Kelvin
You will then get 273 - 273 = 0. We found that 273 K corresponds to 0 ºC.
Advice
- Scientists usually omit the word 'degrees' when using the Kelvin scale. Say '373 Kelvin' instead of '373 degrees Kelvin'.
- For more accurate conversions use 273.15 instead of 273.
- When you need to convert a temperature in degrees Fahrenheit, and high accuracy is not required, subtract 32 from the known temperature and divide the result by 2. For example (100F-32) / 2 = 34 ° C.
-
Any temperature difference will be equal for Kelvin and Celsius. For example, the temperature difference between boiling water and melting ice can be calculated as follows:
- 100 ºC - 0 ºC = 100 ºC o
- 373.15K - 273.15K = 100K
