Fahrenheit to Kelvin Converter

Free instant °F → K converter. No signup, no uploads — everything is calculated privately in your browser.

1 °F = 255.928 kelvin

1 fahrenheit = 255.928 kelvin

Free, instant, and 100% private — every calculation runs in your browser. Nothing is uploaded.

Quick Answer

0°F equals 255.372K; the formula is K = (°F − 32) × 5/9 + 273.15.

Key Facts

  • Formula: K = (°F − 32) × 5/9 + 273.15.
  • Reverse: °F = (K − 273.15) × 9/5 + 32.
  • Reference points: water freezes at 0°C / 32°F / 273.15 K and boils at 100°C / 212°F.
  • Kelvin has no degree symbol and is the SI base unit of temperature.

Fahrenheit to Kelvin Formula

K = (°F − 32) × 5/9 + 273.15

Frequently Asked Questions

K = (°F − 32) × 5/9 + 273.15. Enter the value above and the result appears instantly — the calculation runs entirely in your browser.

K = (°F − 32) × 5/9 + 273.15. To go back the other way, apply the inverse formula — for example 0°F = 255.372K.

1 °F = 255.928 K; 10 °F = 260.928 K; 100 °F = 310.928 K. Use the full conversion table below for more reference values.

At −40 degrees: −40°C and −40°F are the same temperature. That is the only point where the two scales intersect, because the scales have different zero points and step sizes.
