A barometer measures atmospheric pressure. It is measured in various units, one of the oldest being inches of mercury. Other units include pounds per square inch (PSI) kilo-Pascals (kPa) and atmospheres (ATM). Standard pressure is 29.92 inches of mercury, 14.7 PSI, 100 kPa or 1 ATM. Lower barometer readings are generally associated with less stable weather (as in, low pressure system), while higher ones are generally associated with more stable weather (as in, high pressure system).
