What does one centimeter water (4°C) represent?

It represents the hydrostatic pressure from a 1 cm column of pure water at 4°C, commonly approximated as 98.0665 pascals.

Why use pascal [Pa] instead of centimeter water?

Pascal is the SI derived unit widely recognized across scientific, engineering, and meteorological fields for uniform pressure measurement.

Can I use this conversion at temperatures different from 4°C?

No, because water density changes with temperature, the centimeter water (4°C) unit is accurate only near 4°C.

How to Convert from Centimeter water (4°C) to Pascal [Pa]

What Is This Tool?

This tool enables quick and accurate conversion of pressure measurements from centimeter water (4°C) to pascal [Pa]. It caters to users needing to relate small pressure values common in medical, laboratory, and scientific contexts to the standard SI unit for pressure.

How to Use This Tool?

Enter the pressure value in centimeter water (4°C) you wish to convert.
Select pascal [Pa] as the target unit for conversion.
Click the convert button to obtain the equivalent pressure in pascals.

Key Features

Converts from centimeter water (4°C) to pascal [Pa] using an established conversion rate.
Supports pressure unit translation essential in respiratory care, meteorology, and engineering.
Browser-based tool requiring no installation for instant conversions.
Handles small pressure values relevant to precise scientific and medical measurements.

Examples

2 centimeter water (4°C) converts to 196.1276 pascals.
0.5 centimeter water (4°C) converts to 49.0319 pascals.

Common Use Cases

Reporting airway and ventilator pressures such as peak inspiratory pressure and PEEP in respiratory care.
Measuring small hydrostatic or differential pressures using manometers and low-pressure sensors in laboratories.
Setting suction or pressure parameters for medical devices like chest drains and CPAP/BiPAP equipment.
Specifying pressures in meteorological assessments and engineering applications.

Tips & Best Practices

Use this converter when working with small pressure measurements to ensure consistency by expressing values in SI units.
Be mindful that the centimeter water (4°C) unit depends on water density at 4°C and may not apply accurately at other temperatures.
Check the scale of your results in pascals and apply appropriate prefixes (such as kPa or MPa) when dealing with larger pressures.

Limitations

Conversion accuracy relies on the assumption that water temperature is exactly 4°C due to density changes.
Pascal values may vary greatly in magnitude compared to centimeter water requiring careful interpretation of scale.
The tool is limited to converting only between centimeter water (4°C) and pascal [Pa].
