Quick Science Question: °K or K?
So... I know that it's always °C for Celsius and °F for Fahrenheit, but I have a question about Kelvin.
Let's say you have 0°C, which is 32°F, which is also 273°K... or is it just 273 K? My science teacher always writes °K, and so do a few websites I've been on, but Wikipedia and other sites just say K.
I know it's not really a life-threatening question or anything but it's just really annoying me >.<
