Temperature Conversion — Complete Guide
Temperature conversion is one of the most commonly needed unit conversions in everyday life, science, cooking, and engineering. The three primary temperature scales — Celsius, Fahrenheit, and Kelvin — are used in different contexts around the world. Celsius is the global science and everyday standard, Fahrenheit is used for daily weather in the United States and a few other countries, and Kelvin is the absolute temperature scale used in physics, chemistry, and thermodynamics.
Our Temperature Converter provides instant, precise conversion between all three scales. Simply enter a value, select the source unit, and immediately see the equivalent temperatures in the other two scales. Whether you're converting a recipe from Fahrenheit to Celsius, calculating absolute zero in different scales, or checking weather forecasts across international sources, this tool delivers accurate results.
Conversion Formulas
- °C to °F: Multiply by 9/5, then add 32
- °F to °C: Subtract 32, then multiply by 5/9
- °C to K: Add 273.15
- K to °C: Subtract 273.15
Common Reference Points
- Water freezes: 0°C = 32°F = 273.15K
- Water boils: 100°C = 212°F = 373.15K
- Body temperature: 37°C = 98.6°F = 310.15K
- Absolute zero: −273.15°C = −459.67°F = 0K
