What does a centimeter water (4°C) unit measure?

It measures pressure as the hydrostatic pressure from a 1 cm column of pure water at 4°C, commonly used for small pressures in medical and lab contexts.

Why convert from centimeter water to psi?

To translate precise small pressure measurements into a widely recognized unit for force per area commonly used in automotive, hydraulic, and industrial applications.

Can I use this conversion for high-pressure measurements?

Centimeter water is generally suited for small pressure ranges, so it may not be appropriate for high-pressure environments.

Tips & Best Practices

Ensure the temperature is consistent at 4°C for accurate centimeter water readings.
Use psi units when working with Imperial or US customary measurement systems.
Consult calibration standards when converting pressures for medical devices.
Apply conversions cautiously for very high-pressure environments, where other units may be more suitable.

Limitations

Centimeter water (4°C) applies only to water at 4°C and small pressure ranges.
Psi is an Imperial/US customary unit; further conversion might be needed in SI-dominant systems.
Conversion accuracy depends on temperature stability and fluid density assumptions.
