What is a poundal per square foot?

It is a pressure unit from the foot–pound–second system, defined as one poundal of force applied evenly over an area of one square foot.

Why is centimeter water measured at 4°C?

Because at 4°C water reaches its maximum density, providing a standard reference point for hydrostatic pressure measurements.

Can this conversion be used for high-pressure measurements?

No, both poundal/square foot and centimeter water represent low pressures and are generally unsuitable for high-pressure applications.

How to Convert from Poundal/square foot to Centimeter water (4°C)?

Learn how to convert pressure values from poundal per square foot, a unit in the FPS system, to centimeter water (4°C), a medically relevant pressure unit used for small hydrostatic pressures in respiratory and laboratory settings.

What Is This Tool?

This converter transforms pressure measurements from poundal per square foot, a unit from the foot–pound–second system used in legacy engineering, into centimeter water at 4°C, a unit commonly applied in medical and laboratory environments to gauge small pressure differences.

How to Use This Tool?

Enter the pressure value in poundal per square foot.
Select poundal/square foot as the input unit.
Choose centimeter water (4°C) as the output unit.
Submit the input to perform the conversion.
Review the result displayed in centimeter water (4°C).

Key Features

Converts low pressure values from FPS units to medically relevant units.
Includes precise conversion rate between poundal/square foot and centimeter water (4°C).
Supports applications in respiratory care and laboratory pressure measurements.
Browser-based and easy to use without installation.
Provides examples for straightforward understanding.

Examples

10 poundal/square foot equals approximately 0.15175 centimeter water (4°C).
50 poundal/square foot converts to about 0.75877 centimeter water (4°C).

Common Use Cases

Translating legacy FPS pressure data into modern SI-related units for analysis.
Monitoring airway and ventilator pressures in medical respiratory care.
Measuring small hydrostatic pressures in laboratory settings using manometers.
Specifying suction or pressure settings for medical devices like chest drains and CPAP equipment.

Tips & Best Practices

Ensure units are correctly selected to avoid conversion errors.
Use the standard water temperature of 4°C for accurate centimeter water pressure reference.
Be cautious when applying this conversion to high-pressure values as both units represent low pressures.
Understand the legacy nature of poundal/square foot when working with modern systems.
Refer to example conversions to verify correct usage of the tool.

Limitations

Poundal/square foot is uncommon in contemporary practice and may cause confusion.
Centimeter water pressure depends on temperature; deviations from 4°C affect accuracy.
Both units are intended for relatively low pressures, limiting use for high-pressure scenarios.
