What does psi measure?

Psi (pound per square inch) measures pressure as force per unit area and is used mainly in Imperial or US customary systems for applications like tire inflation and hydraulic pressures.

Where is centimeter water (4°C) commonly used?

Centimeter water (4°C) is frequently used in medical and laboratory settings to express small pressures, such as respiratory airway pressures and low hydrostatic measurements.

Why is temperature important for centimeter water units?

Because centimeter water pressure corresponds to the weight of a water column at 4°C, temperature changes can affect the density of water and therefore the pressure value.

What Is This Tool?

This online converter enables users to translate pressure measurements from psi, an Imperial unit used in automotive and hydraulic systems, into centimeter water (4°C), a non-SI unit commonly utilized in medical and laboratory environments for measuring small pressures.

How to Use This Tool?

Enter the pressure value in psi you want to convert.
Select psi as the 'From' unit and centimeter water (4°C) as the 'To' unit.
Click the convert button to see the equivalent pressure in centimeter water (4°C).

Key Features

Converts psi to centimeter water (4°C) reliably using an established conversion factor.
Useful for automotive, industrial, medical, and laboratory applications.
Browser-based tool requiring no installation for convenient access.
Supports accurate representation of pressures across two distinct unit systems.

Examples

1 psi converts to approximately 70.31 centimeter water (4°C).
2 psi converts to approximately 140.62 centimeter water (4°C).

Common Use Cases

Converting automotive tire pressures for clinical respiratory monitoring.
Translating hydraulic system pressures to laboratory-scale pressure units.
Calibrating medical devices such as ventilators and chest drains.
Measuring small hydrostatic pressures in scientific experiments.

Tips & Best Practices

Ensure temperature context when using centimeter water (4°C) since pressure values depend on temperature.
Use this converter when precise small pressure measurements are required in medical and lab settings.
Be cautious converting very high psi values as the resulting centimeter water values can become impractically large.
Verify if SI units are required for compliance before using this conversion.

Limitations

Centimeter water unit depends on the specified temperature of 4°C, so accuracy varies with temperature changes.
Psi is a high-pressure unit; conversions can yield very large values in centimeter water, which may be less practical.
This conversion involves a non-SI unit, which might not meet requirements when SI units are necessary.
