Term Definition
Accuracy Accuracy is defined as the ability of a measurement to match the actual
value of the quantity being measured.
Hecto Pascals (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.
Resolution Resolution is defined as the number of significant digits (decimal
places) to which a value is being reliably measured.
