Temperature Converters

Convert between Celsius, Fahrenheit and Kelvin using the correct offset formulas.

Popular temperature conversions

• Degrees Celsius to degrees Fahrenheit
• Degrees Fahrenheit to degrees Celsius
• Degrees Celsius to kelvins
• Kelvins to degrees Celsius
• Degrees Fahrenheit to kelvins
• Kelvins to degrees Fahrenheit

Units

• Degree Celsius (°C)
• Degree Fahrenheit (°F)
• Kelvin (K)

Notes and definitions

• Temperature scales have different zero points, so conversion is not a simple multiplication.
• Values below absolute zero (0 K = −273.15 °C = −459.67 °F) are rejected.
• Results within about 1e-10 of zero (relative to the intermediate Kelvin value) are snapped to 0 to remove floating-point noise.
