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

Note: Kelvin is an absolute temperature scale, meaning 0 Kelvin is absolute zero, the theoretical absence of all thermal energy. There are no negative temperatures in the Kelvin scale.
