Search, trying to convert temperature from Fahrenheit to Kelvin, such as "87 F to K".
Receive calculated result: "= 0.0265176 Kilometer"
I expected to get an answer in Kelvin, specifically 303.71-ish, not a unit of length.
It's clearly doing feet to kilometer under the hood. This is bad behavior. Neither unit is abbreviated as either of these (F, K). The only standard abbreviations for foot and for kilometer are ft and km, respectively.
Admittedly, degrees Fahrenheit is properly "°F" but F is widely used instead as the degree symbol is difficult to type. Meanwhile, Kelvin is simply "K" as the proper abbreviation.
