Celsius to Fahrenheit Converter

The United States uses degrees Fahrenheit to measure the temperature of almost everything while most of the rest of the world uses degrees Celsius. From your body temperature to cooking temperatures, if you need to convert one unit of measurement to the other, use our converter widget to make an easy calculation.

Converting Units of Temperature Measurement

Fahrenheit (°F) and Celsius (°C) are the units of measurement of the two temperature scales in most common daily usage today. These two different scales of measurement express a range of temperatures from below the freezing point to above the boiling point of water.

Temperature Conversions

Meteorologists, researchers, doctors, students, cooks, and many others often have a need to convert temperatures from one scale to the other. You can make the calculation by using the conversion formulas for each system. However, our widget converter, embedded with the formulas, simplifies the calculation and does the work for you.

Using the Widget Converter

The widget converts both Celsius to Fahrenheit and the reverse:

  • To convert Celsius to Fahrenheit, enter the temperature in degrees Celsius in the first field.
  • To convert Fahrenheit to Celsius, instead enter the temperature in degrees Fahrenheit in the second field.
  • After either line, click the corresponding "Calculate" button to get your answer, either in degrees Fahrenheit or in degrees Celsius.
  • To clear your entries to do a new calculation, click on the "Clear" button.

Making Your Own Calculations

If you want to do your own calculations without the widget, use the conversion formulas as follows:

To convert from Fahrenheit to Celsius:

  • The formula is: Temperature in Celsius = (Temperature in Fahrenheit minus 32) multiplied by the fraction 5/9.
    • That is: °C = (°F - 32) × 5/9
  • Example: Convert 98.6 degrees Fahrenheit to degrees Celsius
    • Calculation: (98.6°F - 32) × 5/9 = 37°C

To convert from Celsius to Fahrenheit:

  • The formula is: Temperature in Fahrenheit = Temperature in Celsius multiplied by the fraction 9/5, then add 32.
    • That is: °F = (°C × 9/5) + 32
  • Example: Convert 37 degrees Celsius to degrees Fahrenheit:
    • Calculation: (37°C × 9/5) + 32 = 98.6°F

Temperatures of Interest

Weather thermometers

The Celsius and Fahrenheit temperature scales have minus 40 degrees (-40°) in common. Otherwise the Fahrenheit scale has a larger number than the Celsius scale to express the same temperature. On the Fahrenheit scale, the interval between the freezing and the boiling point of water is set at 180°, while that of the Celsius scale is set at 100°.

All around the world, the temperature of the day is of interest to people, so they know how to dress for the day, for example, especially as the seasons change. Body temperature is also of interest, as doctors rely on the reading as an indicator of illness or wellness, and even as a sign of fertility.

The following chart displays a sample of interesting temperature measurements.
