Kelvin to Fahrenheit Converter
273.15 K = 32 °F (water freezes). Absolute zero = 0 K = −459.67 °F. Normal body temp = 310.15 K.
Inverse conversion
32 °F = 273.15 K (water freezing). Absolute zero = 0 K = −459.67 °F. Body temperature = 310.15 K.
Formula
Formula
°F = (K − 273.15) × 9/5 + 32
Worked example
To convert 373.15 K (boiling water) to Fahrenheit: (373.15 − 273.15) × 1.8 + 32 = 100 × 1.8 + 32 = 212°F.
