About Temperature Conversion

Temperature is a measure of the average kinetic energy of particles in a substance. Different temperature scales have been developed throughout history for various scientific and everyday applications.

Celsius (°C) is the most widely used temperature scale globally, named after Swedish astronomer Anders Celsius. Fahrenheit (°F) is primarily used in the United States and is named after German physicist Daniel Gabriel Fahrenheit. Kelvin (K) is the SI unit of temperature and is commonly used in scientific applications.

This converter allows you to easily convert temperatures between all three scales. Simply enter a value in any unit and see the equivalent temperatures in all other units instantly.
