Temperature Converter

When values need comparing or a one-off calculation needs checking, this helps students, individuals and professionals. Convert Celsius, Fahrenheit and Kelvin.

Convert Celsius, Fahrenheit and Kelvin. The result appears instantly in your browser, ready to copy, with no account, upload or storage involved.

How to use

Enter the numeric value you want to convert in the first field provided.
Set the source unit as C, F or K, depending on the temperature you already have.
Choose the target unit among Celsius, Fahrenheit and Kelvin in the matching field.
Run the conversion to display the result in the result area.
Copy the converted value, or erase the fields to start again with another measurement.

Example

With an entry such as 100, C as the source unit and F as the target unit, the tool performs the conversion and shows the matching value in the result area. Look there to confirm the target unit and copy the converted temperature.

Input

100
C
F

Output

100 C = 212 F

Limits and formats

The converter only handles Celsius, Fahrenheit and Kelvin; it does not support other temperature scales.
Check both the source and target units, because swapping them produces a very different value.
For regulatory or metrology work, apply your required rounding and precision rules before using the answer.
The tool keeps no history, so copy the result if you need it later.
For a quick comparison, the answer is usually enough; for an official document, check the required method and rounding.

Where processing happens

The whole conversion happens in your browser. The entered value and the selected units are processed locally, and the result appears without being sent or stored elsewhere. You can close the page without leaving the data behind, and no external connection is needed.

Frequently asked questions

Which units can I use?

You can work with the three supported units: Celsius, Fahrenheit and Kelvin. Set the source unit and the target unit, and the tool returns the corresponding temperature value, covering common conversions between these scales.

Is the result rounded?

The displayed result may be rounded for practical use. If you are preparing technical documentation, check the expected precision and compare it with the shown value before using it in a longer calculation.

Is my data sent anywhere?

No. The calculation runs in your browser and nothing is sent outside. The values stay local to the page and are not kept after the operation, even if you close the tab quickly.
