Temperature Converter
Quickly convert values between various temperature units.
Instant Temperature Converter: Celsius, Fahrenheit & Kelvin
Temperature conversion is a daily necessity, from checking the weather in a different country to setting up laboratory experiments. Our converter handles the non-linear math (like the 32-degree offset in Fahrenheit) so you don't have to.
Temperature Conversion Formulas
Our tool uses the following standard formulas for conversion:
- Celsius to Fahrenheit: (C × 9/5) + 32
- Fahrenheit to Celsius: (F − 32) × 5/9
- Celsius to Kelvin: C + 273.15
- Kelvin to Celsius: K − 273.15
When to Use Each Unit?
- Celsius (°C): The global scientific and everyday standard for most countries. Based on the freezing (0°) and boiling (100°) points of water.
- Fahrenheit (°F): Primarily used in the United States. Offers a more granular scale for human-perceived atmospheric temperatures.
- Kelvin (K): The SI base unit for temperature used in physics. Starts at absolute zero, where all molecular motion stops.
