Ever notice how 80 degrees means completely different things depending on the unit? In Fahrenheit, it's a pleasant summer day. In Celsius, you're practically melting. But in Kelvin? Congratulations, you've discovered a new state of matter called "completely frozen solid." Just like my ex's heart.
For the non-science folks: 80°F is about 27°C (warm day), 80°C is 176°F (scalding hot), and 80K is -193°C (colder than liquid nitrogen). This is why scientists insist on units and why the Mars Climate Orbiter crashed in 1999 when someone mixed imperial and metric. A $125 million "oops."
