What Is This Tool?
This converter allows you to transform pressure readings from kilopascal (kPa), a common SI unit for general pressure measurements, into inch water (60°F) (inAq), which is used for detecting very small pressure differences in temperature-dependent environments.
How to Use This Tool?
-
Enter the pressure value in kilopascal (kPa) in the input field
-
Select 'kilopascal [kPa]' as the from-unit and 'inch water (60°F) [inAq]' as the to-unit
-
Click the convert button to receive the equivalent pressure in inch water at 60°F
Key Features
-
Converts pressure values from kilopascal [kPa] to inch water (60°F) [inAq]
-
Supports engineering and HVAC-specific pressure measurements
-
Browser-based and easy to use with quick conversion results
Examples
-
5 kPa equals 20.093 inch water (60°F) (5 × 4.0185980719)
-
10 kPa equals 40.186 inch water (60°F) (10 × 4.0185980719)
Common Use Cases
-
Translating general engineering pressures to fine pressure measurements in HVAC systems
-
Measuring duct and filter pressure drops in ventilation and cleanroom control
-
Specifying low pressures for residential gas services and regulator settings
Tips & Best Practices
-
Use kilopascal for broad pressure reporting and inch water for precise low pressure detection
-
Be aware that inch water measurements are temperature dependent and assume a water temperature of 60°F
-
Apply this conversion in environmental monitoring and pneumatic/hydraulic system diagnostics
Limitations
-
Inch water unit accuracy depends on water density at exactly 60°F, with temperature changes affecting results
-
Kilopascal is a general SI pressure unit and not designed for fluid column-specific measurements
-
The inch water unit is preferable only for small pressure differentials and low-pressure system applications
Frequently Asked Questions
-
Why is inch water (60°F) used for measuring small pressures?
-
Because inch water (60°F) quantifies very small pressure differences and accounts for water density at a specific temperature, it is ideal for precise low-pressure measurements in HVAC and gas service systems.
Key Terminology
-
Kilopascal (kPa)
-
A derived SI unit of pressure equal to 1,000 pascals, measuring force applied per unit area commonly used in engineering and meteorology.
-
Inch water (60°F) [inAq]
-
A pressure unit representing the hydrostatic pressure from a 1-inch water column at 60 °F, used for small differential pressure measurements.
