alt Hacker NewsThe statement that electric pressure cookers measure pressure absolutely (i.e. not relative to local pressure) was news to me, and definitely a good hack to know if you're living at altitude.

Electric cookers don't "measure" pressure. They are thermostatically controlled via a sensor touching the bottom of the bowl and, because they are sealed, that temperature directly translates to the same pressure no matter what altitude you're at.
