Eli5: How does a thermometer on a car work?

950 views

I can’t think of a location within the bodywork of a car that would provide accurate data considering wind-chill when it’s moving, excessive heat from either the engine, or stationary in the sun.

Thermometers aren’t affected by windchill. Windchiil is a phenomenon where we ***feel*** temperature differently than what it really is, because what we feel is a sudden inrush or outrush of heat from our body, or the inability of our body to shed excess heat… not the temperature itself.

For example, when you touch a seatbelt buckle in a car that has been sitting out in the sun, it feels searing hot, but it’s really only around 140°F, and if you could use a good temperature measuring device like a thermocouple to try to measure its temperature, you would indeed get around 140°F. It just feels searing hot because metal is very good at conducting heat.
