How to Use Our Temperature Converter

Temperature conversion is one of the most common daily calculations. Our Temperature Converter converts instantly between Fahrenheit, Celsius, and Kelvin.

How to Convert

Enter a temperature in any of the three scales and the calculator instantly shows the equivalent in the other two. It is that simple.

The Key Formulas

Fahrenheit to Celsius: (F - 32) x 5/9 = C

Celsius to Fahrenheit: (C x 9/5) + 32 = F

Celsius to Kelvin: C + 273.15 = K

Quick Reference Points

| Description | Fahrenheit | Celsius | Kelvin | |------------|-----------|---------|--------| | Water freezes | 32 | 0 | 273.15 | | Room temperature | 68-72 | 20-22 | 293-295 | | Body temperature | 98.6 | 37 | 310.15 | | Water boils | 212 | 100 | 373.15 |

When You Need This

  • Cooking: Many international recipes use Celsius. A 180C oven is 356F.
  • Travel: Most countries outside the US use Celsius for weather. If the forecast says 28C, that is a warm 82F.
  • Science: Scientific measurements use Celsius or Kelvin. Kelvin is essential for physics and chemistry calculations.

Mental Math Shortcut

For a rough Celsius-to-Fahrenheit conversion, double the Celsius value and add 30. It is not exact, but it is close enough for everyday use: 20C becomes roughly 70F (actual: 68F).
