Inch of Water (inH2O) to Standard Atmosphere (atm) Pressure Unit Conversion Calculator
This calculator provides a simple way to convert pressure values from Inch of Water (inH2O) to Standard Atmosphere (atm), a common requirement in scientific, meteorological, and industrial applications involving low-pressure measurements.
Definition: Inch of Water (inH2O)
The Inch of Water (inH2O) is a unit of pressure representing the pressure exerted by a 1-inch column of water under standard gravity. It is commonly used in HVAC, airflow measurements, and fluid flow systems.
Definition: Standard Atmosphere (atm)
The Standard Atmosphere (atm) is a unit of pressure defined as exactly 101,325 Pascals, which is the average atmospheric pressure at sea level. It is widely used in scientific research, engineering, and environmental sciences.
Formula for inH2O to atm Conversion
Pressure in atm=Pressure in inH2O×0.002458
How to Convert inH2O to atm: Example Calculation
Suppose you have a pressure of 50 inH2O. To convert it to atm:
50 inH2O×0.002458=0.1229 atm
So, 50 inH2O is approximately equal to 0.1229 atm.
