Description

Inch of Water (inH₂O): HVAC and Fluid Mechanics

The Inch of Water (inH₂O) is a unit of pressure defined as the pressure exerted by a column of water one inch high, approximately equal to 249.0889 Pascals. It is widely used in the HVAC industry to measure air pressure in ducts and ventilation systems, as well as in fluid mechanics for low-pressure measurements.

Hectopascal (hPa): A Meteorological Standard

The Hectopascal (hPa) is a unit of pressure equal to 100 Pascals. It is commonly used in meteorology to report atmospheric pressure. Since 1 hPa equals 1 millibar, it serves as a direct replacement in weather reports and forecasts. Atmospheric pressure at sea level is typically around 1013 hPa, and variations in this value are crucial for weather prediction.
