hectopaskalia

Hectopascal is a unit of pressure in the metric system. It is equivalent to 100 Pascals. The Pascal (Pa) is the SI derived unit of pressure, defined as one Newton per square meter (N/m²). Therefore, one hectopascal (hPa) is equal to 100 Newtons per square meter. This unit is commonly used in meteorology to measure atmospheric pressure. Weather reports often express atmospheric pressure in hectopascals, where a standard atmospheric pressure at sea level is approximately 1013.25 hectopascals. It is also sometimes referred to as a centibar, as one centibar is equal to 10 hectopascals, though this usage is less common. The hectopascal is a convenient unit for meteorological measurements because it allows for the representation of typical atmospheric pressure values with manageable numbers. For instance, a pressure difference of a few hectopascals can indicate significant changes in weather patterns.
