What is a centipascal (cPa)?

A centipascal is an SI-derived pressure unit equal to one hundredth of a pascal, often used for measuring very small pressure differences in scientific and engineering fields.

What does centimeter mercury (0°C) measure?

Centimeter mercury (0°C) is a pressure unit representing the pressure exerted by a one-centimeter column of mercury at zero degrees Celsius under standard gravity.

Why convert from centipascal to centimeter mercury (0°C)?

Converting helps interpret small pressure measurements in traditional laboratory and industrial contexts that use mercury column-based manometric units.

Browser-based and easy to use interface

Examples

100 cPa converts to approximately 0.00075006375541921 centimeter mercury (0°C)
5000 cPa converts to approximately 0.0375031877709605 centimeter mercury (0°C)

Common Use Cases

Reporting subtle pressure differences in microfluidics and low-pressure gas-flow experiments
Calibrating sensitive differential-pressure sensors such as those used in HVAC control and filter monitoring
Monitoring slight pressure variations in cleanrooms, respiratory systems, and medical devices
Interpreting laboratory readings from mercury column manometers and barometers
Supporting experimental physics and engineering calculations by converting between manometric and SI units

Tips & Best Practices

Ensure input values are accurate and come from calibrated instruments
Confirm standard gravity and temperature conditions when comparing or reporting results
Maintain consistent units across your calculations to avoid errors
Use this tool to bridge older manometric data with modern SI-based measurements
Be aware of environmental factors if precise accuracy is required

Limitations

Conversion assumes standard gravity (9.80665 m/s²) and mercury density at 0°C; deviations may reduce accuracy
Centimeter mercury units are less frequently used in some modern contexts compared to pascals, so unit consistency is important
Results do not account for temperature or local gravitational variations
