About Temperature Conversion
Celsius (°C)
The degree Celsius is a unit of temperature on the Celsius scale, originally known as the centigrade scale. Water freezes at 0°C and boils at 100°C.
Fahrenheit (°F)
The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit. Water freezes at 32°F and boils at 212°F.
Kelvin (K)
The Kelvin is the base unit of temperature in the International System of Units. 0 K is absolute zero, the lowest possible temperature.
Common Formulas
- Celsius to Fahrenheit: (°C × 9/5) + 32 = °F
- Fahrenheit to Celsius: (°F - 32) × 5/9 = °C
- Celsius to Kelvin: °C + 273.15 = K
- Kelvin to Celsius: K - 273.15 = °C
