What does dyne/square centimeter measure?

Dyne per square centimeter is a CGS unit of pressure defined as one dyne of force applied uniformly over one square centimeter.

Why is centimeter water (4°C) used in medical contexts?

Centimeter water (4°C) reflects the hydrostatic pressure exerted by a column of water at 4°C, making it suitable for expressing small pressures in respiratory care and laboratory settings.

Can I use this conversion for any temperature of water?

No, the centimeter water unit specifically uses water at 4°C, where water density is maximal; other temperatures may affect pressure values.

What Is This Tool?

This converter allows you to transform pressure measurements from dyne per square centimeter, a legacy CGS unit, into centimeter water (4°C), a unit commonly used for small pressure differences in medical and laboratory applications.

How to Use This Tool?

Enter the pressure value in dyne/square centimeter
Select dyne/square centimeter as the input unit
Choose centimeter water (4°C) as the output unit
Click the convert button to see the equivalent value
Use the result for scientific, medical, or laboratory purposes

Key Features

Converts pressure values from dyne/square centimeter (dyne/cm²) to centimeter water (4°C)
Uses a precise conversion rate based on defined standards
Supports small pressure measurements relevant in physics, biomedical, and laboratory fields
Facilitates translation of historical scientific data to current medical and lab contexts
Browser-based and easy to use without installation

Examples

10 dyne/square centimeter equals 0.010197443 centimeter water (4°C)
100 dyne/square centimeter equals 0.10197443 centimeter water (4°C)

Common Use Cases

Translating pressure data from CGS system physics to modern hydrostatic pressure units
Reporting airway and ventilator pressures in respiratory care such as peak inspiratory pressure and PEEP
Measuring low pressure differences with manometers in laboratory experiments
Setting suction or pressure parameters for medical devices like chest drains and CPAP/BiPAP machines
Comparing historical pressure data in astrophysics, plasma physics, or materials science with clinical measurements

Tips & Best Practices

Verify that input pressures are small and appropriate for these units
Use the conversion primarily when working across legacy and clinical measurement systems
Confirm temperature conditions, as the centimeter water unit assumes water at 4°C
Cross-check results when precise hydrostatic pressure is critical
Consider modern SI units for broader scientific use outside of stated contexts

Limitations

Dyne/square centimeter is largely obsolete and mainly used in legacy contexts
Differences in water temperature can alter the centimeter water pressure value slightly
Conversion may require careful interpretation in modern scientific or clinical applications
Not suitable for high-pressure measurements beyond the small value range
