Temperature Conversion Calculator

The temperature conversion calculator provideseasy unit conversions among celsius, fahrenheit, and Kelvin temperatures

To convert temperature values from one temperature scale to another use the form on the left. For example, if your question is, “What is 32 degrees Fahrenheit if converted to degrees Celsius or Kelvin?,” enter 32 in the upper left text box labeled “Enter temperature,” and then select °F for the units. The answers appear in the text boxes labeled Celsius and Kelvin. If you do not see the values change after you’ve entered the temperature, just click your mouse anywhere on the form.

The form on the right is needed for temperature values measured relative to another temperature. For example, if a liquid in glass thermometer has scale divisions every 0.2 °F then you might want to know the equivalent spacing in degrees Celsius. The form on the left indicates that 0.2 degrees on the Fahrenheit scale is –17.7 degrees on the Celsius scale. While this answer makes sense in the context of atmospheric temperature, it does not make sense in the context of scale divisions, resolution, accuracy, incremental temperature changes or any other temperature measured relative to another.

For example, if a liquid in glass thermometer has consecutive scale divisions at 100.0 °F and 100.2 °F. The magnitude of a scale division on the thermometer is equal to the difference between 100.2 °F (37.89 °C) and 100.0 °F (37.78 °C). In this context 0.2 °F is equivalent to 0.11 °C, not –17.7 °C.
