Temperature Converter
Celsius, Fahrenheit, Kelvin — convert any way, with reference points for weather and cooking.
0 Celsius (°C) =
32 Fahrenheit (°F)
Three Scales, Any Direction
Convert freely between Celsius (°C), Fahrenheit (°F), and Kelvin (K). Useful for cooking, travel, weather, and science.
Handy Reference Points
- Water freezes: 0°C = 32°F = 273.15 K
- Room temperature: 20°C = 68°F
- Body temperature: 37°C = 98.6°F
- Water boils: 100°C = 212°F = 373.15 K
Frequently Asked Questions
How do I convert Celsius to Fahrenheit?
°F = °C × 9/5 + 32. So 0°C = 32°F, 100°C = 212°F, and body temperature 37°C = 98.6°F.
How do I convert Fahrenheit to Celsius?
°C = (°F − 32) × 5/9. A 72°F room ≈ 22°C; 100°F fever ≈ 37.8°C.
What is Kelvin used for?
Scientific measurements. 0 K is absolute zero (−273.15°C). Lab and physics contexts almost always use Kelvin.
Is there a shortcut for mental conversion?
Rough: double the °C and add 30 to estimate °F. 20°C → 70°F (actual 68°F). Good enough for weather.
