What instrument is used to measure atmospheric pressure?

Explanation:
Measuring atmospheric pressure relies on an instrument that responds to the weight of the air above us. A barometer does exactly that by translating air pressure into a readable value. This is essential for understanding weather changes and altitude effects, with readings often given in millibars or kilopascals. The other tools have different purposes: a hygrometer measures humidity, an anemometer gauges wind speed, and a thermometer records temperature. Therefore, the barometer is the instrument used to measure atmospheric pressure.
