What is a Temperature Converter?
A temperature converter helps you switch between temperature scales — Celsius, Fahrenheit, Kelvin, and Rankine. Whether you're cooking, doing science homework, or checking international weather, this tool gives you instant accurate conversions.
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
- Kelvin to Fahrenheit: °F = (K − 273.15) × 9/5 + 32
Common Temperature References
- 0°C = 32°F (water freezes)
- 100°C = 212°F (water boils)
- 37°C = 98.6°F (body temperature)
- 25°C = 77°F (room temperature)
- Absolute Zero = -273.15°C = -459.67°F = 0 K
