This free online temperature converter will convert Celsius to Fahrenheit, Fahrenheit to Kelvin, Kelvin to Celsius, as well as the reverse of all three conversions.
Plus, unlike other online temp converters, this temp converter will show the formula and step-by-step math it used to complete the conversion.
Finally, the temperature conversion calculator also provides a feature that will allow you to create your own custom, printable, temp conversion chart. Just select the scale you are converting from and to, enter the desired starting and ending temperatures, and click the button. Cool!
Each of the following examples lists the temperature conversion formula for the corresponding type, plus solves for the unknown variable.
|C = 15°, F = ?|
|C to F Formula:||F||=||C x 9/5 + 32|
|F||=||15 x 1.8 + 32|
|F||=||27 + 32|
|50°F = ?°C|
|F to C Formula:||C||=||(F - 32) x (5/9)|
|C||=||(50 - 32) x (5/9)|
|C||=||18 x .56|
|10°C = ? Kelvin|
|C to K Formula:||K||=||C + 273.15|
|K||=||10 + 273.15|
|325 Kelvin = ?°C|
|K to C Formula:||C||=||K - 273.15|
|C||=||325 - 273.15|
|50°F = ? Kelvin|
|F to K Formula:||K||=||(F + 459.67) x (5/9)|
|K||=||(50 + 459.67) x (5/9)|
|K||=||509.67 x .56|
|260 Kelvin = ?°F|
|K to F Formula:||F||=||(K x 9/5) - 459.67|
|F||=||(260 x 1.8) - 459.67|
|F||=||468 - 459.67|
The following chart compares the three most common benchmarks for each temperature scale:
|Avg. Room Temp:||68||20||293|
With that, let's use the Temperature Conversion Calculator to convert between Celsius, Fahrenheit, and Kelvin, or to create a custom, printable temp conversion chart.

To Help You To
Celsius: Temperature scale wherein 0°C is the freezing point, 100°C is the boiling point, and average room temperature is 20°C. The Celsius scale is used primarily outside the U.S.
Fahrenheit: Temperature scale wherein 32°F is the freezing point, 212°F is the boiling point, and average room temperature is 68°F. The Fahrenheit scale is primarily used in the U.S.
Kelvin: Absolute temperature scale wherein 273 Kelvin is the freezing point, 373 Kelvin is the boiling point, and average room temperature is 293 Kelvin. The Kelvin scale is based on absolute zero (-273.15°C) -- which also means the Kelvin scale has no negative units (does not use the term degrees).
Temp conversion options: Click the button next to the desired conversion option. The temperature conversion calculator will then rename the fields according to your selection. Note that Celsius is also referred to as centigrade, so centigrade to Fahrenheit conversion is the same as Celsius to Fahrenheit.
Enter temperature: Enter the temperature units/degrees to convert from the type listed in bold on in this line.
Equivalent temperature: This is the temperature converted to the type listed in bold on line this field is located on.
Printable Temp Conversion Chart: To create a custom temperature conversion chart that you can print out, select the conversion type from the drop-down menu and enter the starting and ending temperature of the first letter appearing in the selected conversion type. Then click this button.
