How do I convert Fahrenheit to Kelvin?

Use the formula K = (°F − 32) × 5/9 + 273.15. First subtract 32 and scale to Celsius, then add 273.15 to reach the absolute Kelvin scale. For example, 32 °F = 273.15 K.

Is this converter accurate?

Yes. It applies the exact two-step relation (°F − 32) × 5/9 + 273.15 — note the additive offset, which makes temperature conversions non-proportional.

Is my data sent anywhere?

No. The converter is privacy-first — every calculation runs locally in your browser and nothing you type is transmitted or stored.
