Note: Hectopascal (hPa) is the barometric pressure unit recom-
mended by WMO and also accepted by ISO.
1 hPa = 1 mbar

* Defined as ±2 standard deviation limits of end-point
non-linearity, hysteresis error or repeatability error
** Defined as ±2 standard deviation limits of inaccuracy
of the working standard at 1000 hPa including traceability
to NIST
*** Defined as the root sum of the squares (RSS) of end-
point non-linearity, hysteresis error, repeatability error
and calibration uncertainty at room temperature
