For quick °F to °C conversion: subtract 32, then halve it
Kelvin is used in science because it starts at absolute zero
High humidity can make temperatures feel 10-15°F warmer
Absolute zero (-273.15°C) is the coldest possible temperature where molecular motion stops.
Water boils at lower temperatures at higher altitudes due to decreased atmospheric pressure.
The Sun's core reaches about 15 million °C (27 million °F) - hot enough for nuclear fusion.
