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.
