What Is This Tool?
This tool allows you to convert pressure measurements from centipascal (cPa), a unit for very small pressures, to inch water (60°F) (inAq), a unit often applied in HVAC and gas service settings.
How to Use This Tool?
-
Enter the pressure value in centipascal [cPa]
-
Select the target unit as inch water (60°F) [inAq]
-
Initiate the conversion to view the equivalent value
-
Use the results to interpret small pressure differences in practical systems
Key Features
-
Converts small pressure units centipascal to inch water (60°F)
-
Supports applications in HVAC, cleanroom monitoring, and gas regulation
-
Browser-based and easy to use with clear input and output fields
-
Provides conversion formulas and example calculations
Examples
-
100 cPa converts to 0.0040186 inAq
-
250 cPa converts to 0.0100465 inAq
Common Use Cases
-
Reporting minute pressure differences in microfluidics and low-pressure gas flows
-
Calibrating sensitive differential-pressure sensors for HVAC and filtration systems
-
Monitoring pressure changes in cleanrooms, respiratory devices, and residential gas settings
Tips & Best Practices
-
Ensure accurate input values due to the small numerical scale of centipascal units
-
Consider temperature dependence when interpreting inch water (60°F) measurements
-
Use precise instruments to detect and convert very low pressure differences
Limitations
-
Inch water measurements vary with temperature since water density changes
-
Centipascal units represent very small pressures that may require sensitive tools
-
Conversions can result in tiny values requiring careful handling of decimal accuracy
Frequently Asked Questions
-
What is a centipascal used for?
-
Centipascal is used to measure very small pressures or pressure differences, commonly in scientific and engineering fields such as microfluidics and sensitive sensor calibration.
-
Why does inch water pressure depend on temperature?
-
Inch water pressure is temperature-dependent because the density of water changes with temperature, affecting the hydrostatic pressure of a given water column.
-
Can I use this tool for HVAC and gas service applications?
-
Yes, this converter helps express small pressure differences in units compatible with HVAC duct pressure measurements and gas regulator settings.
Key Terminology
-
Centipascal [cPa]
-
An SI-derived unit of pressure equal to one hundredth of a pascal, used for very small pressure measurements.
-
Inch water (60°F) [inAq]
-
A pressure unit representing the pressure exerted by a 1-inch column of water at 60°F, accounting for temperature-dependent water density.
-
Differential-pressure sensor
-
A device that measures the difference in pressure between two points, often used in HVAC and cleanroom environments.
