Hectopascal (hPa) is a metric (SI) measurement unit of pressure. The hectopascal is equivalent to millibar and commonly used to measure atmospheric pressure.Click to see full answer. Moreover, what does a 1000 hPa mean?1000 hPa are equal to 1000 mbar, which is equal to 750 mm of mercury in a barometric column, which is 0.987 of the average atmospheric pressure, which on global average is 1013 millibars or hectopascals. While hPa is used in meteorology most weatherforecasts quote atmospheric pressure in millibar.Furthermore, is 1016 hPa high pressure? The average value of atmospheric pressure over Ireland is about 1013 hectopascals. It is generally higher in summer than in winter, with monthly averages varying from a low of 1011 hPa in December and January, to a high of about 1016 in mid summer. High values of atmospheric pressure are associated with anticyclones. In respect to this, what is a hPa? hPa is the abbreviated name for hectopascal (100 x 1 pascal) pressure units which are exactly equal to millibar pressure unit (mb or mbar).How is hPa calculated?Use hectopascals (hPa) in the equation. Multiply the atmospheric pressure in hectopascals times 100 using a scientific calculator. For example, the pressure is 1037 hPa: 1037 x 100 = 103700. Divide your answer by 101325 using a scientific calculator.
