What does one dekapascal represent?

One dekapascal (daPa) is an SI-derived pressure unit equal to 10 pascals, measuring force per unit area.

Why is centimeter water measured at 4°C?

Centimeter water is defined at 4°C because this is where water has maximum density, providing a standard hydrostatic pressure reference.

In which fields is this pressure conversion commonly used?

It is widely used in audiology, HVAC diagnostics, medical respiratory care, and laboratory pressure sensor calibration.

What Is This Tool?

This converter facilitates transforming pressure values from dekapascal (daPa), an SI-derived unit, into centimeter water at 4°C, a hydrostatic pressure measure commonly used in medical and laboratory fields.

How to Use This Tool?

Enter the pressure value in dekapascal [daPa] into the input field.
Select the target unit as centimeter water (4°C) if not preselected.
Click the convert button to see the equivalent pressure in centimeter water (4°C).
Use the result for applications in medical, laboratory, or HVAC contexts.

Key Features

Supports conversion of pressure between dekapascal and centimeter water (4°C).
Provides a precise conversion factor based on recognized pressure standards.
Useful for medical respiratory settings, audiology, HVAC, and laboratory applications.
Browser-based and easy to use without additional software.
Enables consistent translation of low-pressure measurements across units.

Examples

Converting 5 daPa results in approximately 0.50987 cm H2O (4°C).
Converting 10 daPa results in approximately 1.01974 cm H2O (4°C).

Common Use Cases

Translating audiology middle-ear pressure measurements reported in daPa into centimeter water units.
Converting small pressure differentials in HVAC systems and cleanroom filters for diagnostics.
Calibrating and specifying low-pressure sensors and pneumatic equipment in laboratories.
Reporting airway and ventilator pressures such as peak inspiratory pressure or PEEP in respiratory care.
Setting suction and pressure values for medical devices like chest drains and CPAP machines.

Tips & Best Practices

Ensure temperature conditions match 4°C when interpreting centimeter water pressure values.
Use the tool primarily for low-pressure measurements aligned with device specifications.
Verify unit selections before converting to maintain accuracy and relevance.
Apply the results consistently across clinical or laboratory records for standardization.

Limitations

Centimeter water pressure values depend on water density at 4°C and may vary with temperature changes.
Conversion factors involve approximations which might introduce slight rounding differences.
Not suitable for converting high-pressure values; designed for low-pressure ranges.
