What Is This Tool?
This tool allows you to convert pressure measurements from centimeter water (4°C), a unit used mainly in medical and lab settings, into dekapascal [daPa], an SI-derived pressure unit. It helps translate small hydrostatic and medical pressure readings into standard, universally recognized units.
How to Use This Tool?
-
Enter the pressure value in centimeter water (4°C)
-
Select centimeter water (4°C) as the input unit
-
Choose dekapascal [daPa] as the output unit
-
Click convert to get the equivalent pressure in dekapascal
Key Features
-
Converts centimeter water (4°C) pressure values to dekapascal [daPa]
-
Supports small pressure and pressure difference measurements
-
Browser-based and user-friendly for quick conversions
-
Useful for applications in respiratory care, audiology, and laboratory settings
Examples
-
1 centimeter water (4°C) equals 9.80638 dekapascal
-
5 centimeters water (4°C) corresponds to 49.0319 dekapascal
Common Use Cases
-
Reporting airway and ventilator pressures in respiratory care
-
Measuring small differential pressures in laboratories
-
Setting suction and pressure levels on medical devices like CPAP or chest drains
-
Monitoring middle-ear pressures in audiology using tympanometry
-
Performing HVAC and cleanroom filter pressure diagnostics
Tips & Best Practices
-
Ensure measurements are made at or near 4°C for accuracy with centimeter water unit
-
Use the converted dekapascal values for standardized reporting and calibration
-
Cross-check instrument accuracy when working with very small pressure values
-
Apply this conversion mainly in clinical, laboratory, and engineering contexts
Limitations
-
Centimeter water unit depends on water density at exactly 4°C, which may vary with temperature
-
Conversion precision can be influenced by instrument measurement accuracy
-
Dekapascal units are better suited for slightly larger pressure ranges than very small differentials
Frequently Asked Questions
-
What is a centimeter water (4°C) unit?
-
It is a pressure unit defined by the hydrostatic pressure exerted by a 1 cm column of pure water at 4°C, mainly used in medical and laboratory pressure measurements.
-
Why convert from centimeter water (4°C) to dekapascal?
-
Converting to dekapascal standardizes small pressure values into an SI-derived unit, facilitating comparison, reporting, and calibration in various fields.
-
Where is dekapascal commonly used?
-
Dekapascal is used in audiology for middle-ear pressure, HVAC systems, cleanroom filter monitoring, and low-pressure sensor calibration.
Key Terminology
-
Centimeter water (4°C)
-
A non-SI pressure unit based on the hydrostatic pressure from 1 cm column of water at 4°C, used in medical and laboratory contexts.
-
Dekapascal (daPa)
-
An SI-derived unit of pressure equal to 10 pascals, often used in small pressure measurements in audiology and HVAC.
