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

It represents small pressure values relevant to respiratory care and lab measurements, such as airway pressure and ventilator settings.

What does pound-force per square inch measure?

It is an imperial unit measuring pressure as force applied over a square inch, commonly used in engineering and everyday applications like tire pressure.

Can I convert pressures measured at temperatures other than 4°C directly?

Since centimeter water (4°C) is defined at that specific temperature, conversions from measurements at different temperatures might not be precise.

How to Use This Tool?

Enter the pressure value in centimeter water (4°C) you want to convert.
Select the target unit as pound-force per square inch (psi).
Click convert to get the equivalent pressure value in psi.

Key Features

Converts pressure values specifically from centimeter water (4°C) to pound-force per square inch.
Supports pressure measurement applications from medical respiratory care to hydraulic system design.
Provides quick and easy conversion with a clear formula and example calculations.

Examples

5 centimeter water (4°C) converts to approximately 0.0711 pound-force per square inch.
10 centimeter water (4°C) is equal to about 0.1422 pound-force per square inch.

Common Use Cases

Translating airway and ventilator pressure measurements in respiratory care into psi for engineering compatibility.
Measuring small hydrostatic pressures in laboratories and converting them for industrial use.
Checking automotive tire pressures and hydraulic system pressures using psi from medical or lab pressure data.

Tips & Best Practices

Ensure the input pressure is measured at or adjusted for 4°C to maintain conversion relevance.
Use precision instruments when working with small pressure values to obtain accurate readings after conversion.
Understand the context of the units, especially the physiological or engineering requirements, for correct interpretation.

Limitations

Conversion results in small decimal values due to the low magnitude of centimeter water (4°C).
The unit centimeter water (4°C) is temperature-specific; pressure readings at different temperatures may not convert accurately.
High precision measuring tools are recommended for interpreting converted psi values.
