	Hectopascals? No! No! Never!
		That clearly is not the case with hectopascals, since the pascal as a special name for newtons per square metre was not introduced until the 1970s.
		To use hectopascals in aviation meteorology is to miss out on one of the major advantages of the International System of Units, not having to learn a whole new set of units for each field of endeavor.
		A special problem with the unfamiliarity of hectopascals is the commonly seen misuse of capitalization in the name of this unit.

	SENSOR_pressure (Site not responding. Last check: 2007-10-10)
		In meteorology the quotient is measured in Hectopascal - formerly also in millimeter mercury - as the unit force of an air column pressing on a surface unit.
		Pressure and pressure tendency are the most important meteorological parameters because they give us an idea of the quantity of a high (Anticyclone) or low pressure (Cyclone) systems as well as the movement of these atmospheric systems and the accompanying cold and warm fronts.
		Pressure measurement therefore has to be carried out very carefully because already a tenth of Hectopascal causes deformation in the analysis of the pressure field if the measurement is not quite correct.

	Pascal - Wikipedia, the free encyclopedia
		After the introduction of SI units, many preferred to preserve the customary pressure figures.
		Therefore, meteorologists use hectopascals today for air pressure, which are equivalent to millibars, while similar pressures are given in kilopascals in practically all other fields, where the hecto prefix is hardly ever used.
		1 hectopascal (hPa) = 100 Pa = 1 mbar.

	BoM-Bureau of Meteorology - The Aneroid Barometer
		For example, if the barometer reads 1020 hectopascals at the sea coast and you drive along a mountain road 325 metres high, the pointer should move down the scale to about 980 hectopascals.
		Your barometer will most likely be marked in tens of hectopascals (990, 1000, 1010 etc.) with further graduations given for each hectopascal, which enable it to be read reasonably easily to the nearest half hectopascal.
		One hectopascal is exactly equal to one millibar, the unit of pressure mainly used for barometer scales before 1986.

	Pressure - Pressure (Site not responding. Last check: 2007-10-10)
		In meteorology today, pressure is not expressed in pounds per square inch, but in a unit known as a hectopascal (hPa) which is the same as the old term millibar.
		One hectopascal is a pressure of 1000 dynes per square centimeter, where the dyne is a metric unit of force.
		Expressed in hectopascals, the pressure of the atmosphere at sea level is about 1 000 hectopascals, but may vary from about 960 hPa to 1050 hPa.

	The Daily CIMSS Regional Assimilation System Forecast
		A "hectopascal" (hPa), is a unit of measurement used by meteorologists to define pressure levels.
		In this case, the 850 hPa level, defines the "middle" portion of the atmosphere (the lower atmosphere being the surface, roughly 1000 hPa, and the upper atmosphere, being less than 300 hPa).
		In this case, at the 700 hPa level, the CRAS model outputs windspeed, measured in "knots" (kts), geopotenial height, measured in "millibars" (mb), and Omega, a diagonistic variable that defines the vertical velocity in pressure units.

	hectopascals
		The exceptions are the basic units of length, mass and time, ie the metre, gramme and second.
		Following the adoption of the Pascal as the SI unit of pressure, meteorologists chose the hectopascal as the international unit for measuring atmospheric pressure.
		(1 hPa = 100 pascals = 1 mb.) The millibar is still often used in weather reports and forecasts for the public, but the term hectopascal is increasingly being used, especially on the Continent in general and France, in particular.

		Forgetting that our altimeters have settings for millibars and hectopascal (which I had only used once in my career, and that was 6 months ago), I asked where the conversion chart was.
		Obtaining altimeter settings and landing data closer to the approach segment complicates the task of preparing data for landing at the very time the flight crew may be most fatigued.
		The term "hectopascal" is derived partly from the name of a 17th century philosopher and mathematician, and partly from the Greek.

	Met Office: Interpreting weather maps
		Meteorologists measure pressure in units of millibars (mb), though instruments sometimes give pressures in terms of inches of mercury.
		The term hectopascal (hPa) is often used instead of millibar, where 1 millibar equals 1 hectopascal.
		In the British Isles the average sea-level pressure is about 1013 mb (about 30 inches of mercury), and it is rare for pressure to rise above 1050 mb or fall below 950 mb.

		The unit of force measurement is the millibar (mb), sometimes (and increasingly) called the hectoPascal.
