­A barometer measures air pressure: A "rising" barometer indicates increas­ing air pressure; a "falling" barometer indicates decreasing air pressure. In space, there is a nearly complete vacuum so the air pressure is zero.


A barometer measures atmospheric pressure in units of measurement called atmospheres or bars. An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit).

Make a barometer | DIY Activity Activity Steps What is a barometer and what does it measure? A Barometer is an instrument that is used to measure the air pressure around us. Pressure is important as it can tell us about what kind of weather to expect; when the pressure is high, we can usually expect clear skies and light winds, when the pressure is Meteorologists measure these changes in the air to forecast weather, and the tool they use is a barometer. The common units of measurement that barometers use are millibars (mb) or inches of mercury.
