Fahrenheit to Kelvin (°F to K)
Convert °F to K — Temperature converter
Also written as F to K.
Converting Fahrenheit to Kelvin uses the formula K = (°F − 32) × 5/9 + 273.15. Both are temperature scales that measure how hot or cold something is, so the change is a formula rather than a single multiplier. A few reference points: 0 °F = 255.372222 K, 37 °F = 275.927778 K, and 100 °F = 310.927778 K.
