Why is inch water pressure specified at 60°F?

Because water density changes with temperature, inch water pressure readings are temperature-specific to 60°F for consistent and accurate measurement.

Where is the pascal commonly used?

Pascal is widely used in engineering, physics, meteorology, and hydraulics to quantify pressure and mechanical stress.

What applications use inch water (60°F) units?

Inch water (60°F) units are used in HVAC system pressure measurements, residential gas service, and cleanroom ventilation control.

Click the convert button to see the equivalent pressure in inch water (60°F).

Key Features

Converts pressure values from pascals to inch water (60°F).
Supports measurements relevant to engineering, meteorology, HVAC, and gas service.
Uses a standardized conversion rate based on water column pressure at specified temperature.
Browser-based and straightforward-to-use interface.
Helps interpret low pressure readings important in ventilation and cleanroom environments.

Examples

100 Pa converts to approximately 0.40186 inAq.
250 Pa converts to approximately 1.00465 inAq.

Common Use Cases

Measuring low pressure drops in HVAC duct and filter systems.
Determining residential gas service pressures and regulator settings.
Reading differential pressure sensors and manometers in ventilation and cleanroom controls.

Tips & Best Practices

Ensure that pressure readings using inch water are referenced to 60°F to maintain accuracy.
Use this conversion when precise low-pressure measurements are needed in engineered or environmental applications.
Calibrate instruments regularly, especially when working with low-pressure differentials.

Limitations

Inch water (60°F) depends on water density at the specified temperature, limiting conversions to environments at or near 60°F.
Pascal is not ideal alone for expressing very low pressures without conversion to more practical units like inch water.
Low-pressure readings require careful calibration and consideration of fluid properties to ensure accuracy.
