What is a temperature converter?
A temperature converter is an online tool that lets you convert temperatures between Celsius, Fahrenheit and Kelvin scales. It is especially useful when travelling, studying or working with international data.
How to convert temperature units?
Select the source scale, enter a temperature value and choose the target scale. The converter instantly calculates the precise result.
What are the temperature conversion formulas?
Key temperature conversion formulas:
- Celsius to Fahrenheit: °F = °C × 9/5 + 32
- Fahrenheit to Celsius: °C = (°F − 32) × 5/9
- Celsius to Kelvin: K = °C + 273.15
- Kelvin to Celsius: °C = K − 273.15
- Fahrenheit to Kelvin: K = (°F − 32) × 5/9 + 273.15
What are some temperature conversion examples?
Body temperature: 36.6 °C = 97.88 °F. Normal human body temperature.
Boiling point of water: 100 °C = 212 °F = 373.15 K.
Cold winter day: −20 °C = −4 °F. A typical winter temperature in northern climates.
When is a temperature converter useful?
A temperature converter is useful when travelling to countries that use Fahrenheit, reading scientific papers with Kelvin values, following cooking recipes from abroad or checking weather forecasts in different temperature scales.
Which countries still use Fahrenheit instead of Celsius?
Only a small number of countries officially use Fahrenheit: the United States, the Bahamas, the Cayman Islands, Palau, and a few Pacific island nations. The rest of the world — including all of Europe — uses Celsius. Kelvin is reserved for science and engineering worldwide. When following international recipes, the cooking unit converter and energy converter can also come in handy alongside temperature conversions.
