Barometer vs. Thermometer: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
A barometer measures atmospheric pressure, indicating weather changes, while a thermometer measures temperature.
Key Differences
A barometer is an instrument used to measure atmospheric pressure, providing insights into weather conditions. A thermometer, in contrast, is used to measure the temperature of a substance or environment, indicating heat intensity.
