In aviation, weather reports ( METAR ), QNH is transmitted around the world in millibars or hectopascals (1 hectopascal = 1 millibar), except in the United States , Canada , and Colombia where it is reported in inches of mercury (to two decimal places). Using ISA standards, the defaults for pressure and temperature at sea level are 101,325 Pa and 288 K. Calculates the sea-level pressure from the atmospheric pressure, temperature and altitude at the present location. The atmospheric pressure shown on the weather map is adjusted to the equivalent sea level pressure. (1atm=1013.25hPa) at present location: Altitude h.

2012-12-19 · On the top of Mount Everest, the total atmospheric pressure is reduced to 33.73 kPa (about one-third of its value at sea level). Assume that the fraction of the atmosphere that is made up of oxygen is the same at all elevations. Kilopascal (kPa) Conversion: Kilopascal (kPa) is a frequently used pressure unit and equals to 1000 newton per square meter (metre). 1 kPa = 0.00986923 atm → kPa to atm; 1 kPa = 0.01 bar → kPa to bar; 1 kPa = 0.01019716213 kg/cm² → kPa to kg/cm²; 1 kPa = 0.001 MPa → kPa to MPa; 1 kPa = 1000 pascals → kPa to pascal (illum) Illuminated P 63 MSL Mean Sea Level H 6 IMO International Maritime Organization — Mth.

kPa. The conversion of units is an important concept in physics. We know that a pascal is a derived unit of pressure. The highest sea-level pressure on Earth occurs in Siberia, where the Siberian High often attains a sea-level pressure above 1032.0 mbar. The lowest measurable sea-level pressure is found at the centers of hurricanes (typhoons, baguios). Atmospheric pressure variation [edit | edit source] Hurricane Wilma on October 19, 2005 – 88.2 kPa in eye The Standard Atmospheric Pressure is defined at sea-level at 273 o K (0 o C) and is 1.01325 bar or 101325 Pa (absolute).

The kPa is mostly used for describing sub-atmospheric air pressures and low differential air pressures found in building ventilation systems. When compared to bar unit there is 100 kPa in 1 bar which happens to be very close to the standard atmospheric pressure at sea level (101.325kPa), therefore a reading in kPa closely represents the same value as the 0 to 100 percentage scale of atmospheric pressure. 101.325 kPa. US customary units. 14.69595 psi. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101 325 Pa ( 1.013 25 bar). It is sometimes used as a reference pressure or standard pressure.
