Relative barometric pressure, corrected to sea-level.
To compare pressure conditions from one location to
another, meteorologists correct pressure to sea-level
conditions. Because the air pressure decreases as you
rise in altitude, the sea-level corrected pressure (the
pressure your location would be at if located at
sea-level) is generally higher than your measured
pressure.
Accuracy is defined as the ability of a measurement to
match the actual value of the quantity being measured.
Pressure units in SI (international system) units of
measurement. Same as millibars (1 hPa = 1 mbar)
A hygrometer is a device that measures relative
humidity. Relative humidity is a term used to describe
the amount or percentage of water vapor that exists in
air.
Pressure in Imperial units of measure.
1 inch of mercury = 33.86 millibars
Range is defined as the amount or extent a value can be
measured.
Measured barometric pressure relative to your location
or ambient conditions.
