Barometric Pressure
Different Units:
Atmospheric conditions can be measured in many different units; for example at an altitude of 160 meters in Leimen on a sunny day in May/2024 the following measurements were taken:
14 psi (pounds per square inch) = 99'368 Pa (standard atmospheric unit of Pascals) = 30 inHg (inches of mercury) = 745 mmHg (millimeters of mercury) = 994 mb (MilliBars)

Usually the domestic atmospheric pressure ranges between 720-800 mmHg = 960-1070 mb. The higher the value, the sunnier (or dryer) the weather is!

Meteorological Reports:
The international standard unit for measuring atmospheric pressure is the pascal (Pa). In meteorology, pressure is often measured in HectoPascals (hPa) or millibars (mb), where 1 hPa = 100 pascals. The value of the atmospheric pressure at sea-level is on average around 1'013.25 hPa {aka 1 atmosphere = 1 atm}.
Low-pressure events refer to atmospheric pressure values lower than the average sea-level pressure. They typically have readings between roughly 1000 mb to as low as 980 mb.
- High-pressure events refer to atmospheric pressure values higher than the average sea-level pressure. High-pressure systems commonly range from about 1020 to 1040 mb.
