Accuracy Accuracy is defined as the ability of a measurement to match the actual
value of the quantity being measured.
HectoPascals (hPa) Pressure units in SI (international system) units of measurement. Same
as millibars (1 hPa = 1 mbar)
Hygrometer 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.
Inches of Mercury (inHg) Pressure in Imperial units of measure.
1 inch of mercury = 33.86 millibars
Range Range is defined as the amount or extent a value can be measured.
Relative Barometric
Pressure
Measured barometric pressure relative to your location or ambient
conditions.
