How Celsius, Fahrenheit, and Kelvin conversion works

This temperature converter changes values between Celsius, Fahrenheit, and Kelvin. It is useful for weather, baking, science, air-conditioning settings, equipment specifications, and international references.

Celsius and Fahrenheit use different zero points and scale sizes, so they cannot be converted by adding a single fixed amount. Kelvin is common in science and engineering.

Formula or logic

  • Fahrenheit = Celsius × 9/5 + 32
  • Celsius = (Fahrenheit - 32) × 5/9
  • Kelvin = Celsius + 273.15

Example

If the temperature is 30°C, it is about 86°F. If a scientific reference says 300 K, that is about 26.85°C.

Common questions

What is 0°C in Fahrenheit?

0°C equals 32°F.

What is 100°F in Celsius?

100°F is about 37.78°C.

Can Kelvin be negative?

In normal physical meaning, Kelvin cannot be below 0 K, which is absolute zero.
