Kelvin to FahrenheitK → °F

Formula: °F = (K − 273.15) × 9/5 + 32

Formula

°F = (K − 273.15) × 9/5 + 32

Example: 273.15 K = 32 °F

Temperature scales start from different zero points, so converting is more than multiplying: shift to a common zero (absolute zero, in kelvin), then scale by the size of a degree. That’s why 0 °C is 32 °F, not 0 °F.
