Convert Kelvin to Fahrenheit
Kelvin (K) to Fahrenheit (°F) — the formula, a worked example and a live converter, all in your browser.
Kelvin to Fahrenheit formula
Temperature scales don't share a zero point, so the conversion uses an offset formula rather than a simple ratio:
°F = (K − 273.15) × 9/5 + 32
Worked example
20 K = 20 = -423.67 °F.
