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