About Temperature Converter
Zeta Calculator's Temperature Converter is a simple yet powerful tool designed to help you convert between different temperature scales quickly and accurately. Whether you're converting Celsius to Fahrenheit, Fahrenheit to Kelvin, or any other combination, our tool provides instant results.
Supported Units
- Celsius (°C): The standard metric temperature scale where water freezes at 0°C and boils at 100°C
- Fahrenheit (°F): Temperature scale used in the United States where water freezes at 32°F and boils at 212°F
- Kelvin (K): The SI base unit of temperature, with 0K representing absolute zero (-273.15°C)
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
How to Use
- Enter the temperature in the input field
- Select the source unit (what you're converting from)
- Select the target unit (what you're converting to)
- Click "Convert" or press Enter to see the result
- Use "Swap Units" to quickly reverse the conversion
