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

It is the pressure exerted by a 1-foot column of pure water at 4°C, used as a reference for low-pressure measurements.

Why use centipascal units?

Centipascal is an SI unit best suited for expressing very small pressure differences in scientific and engineering applications.

Can I use this conversion for high-pressure systems?

No, this conversion is most suitable for low pressures since centipascal measures very small pressure values.

Examples

To convert 2 ftAq to cPa, multiply 2 by 298898 to get 597796 cPa
To convert 0.5 ftAq to cPa, multiply 0.5 by 298898 to obtain 149449 cPa

Common Use Cases

Specifying hydraulic head and low pressures for pumps and water-distribution systems
Interpreting readings from manometers or gauges in laboratories and HVAC systems
Expressing static head or depth-pressure relations in groundwater and well measurements
Calibrating sensitive differential-pressure sensors in scientific instrumentation
Monitoring slight pressure changes in cleanrooms and medical equipment

Tips & Best Practices

Ensure the foot water measurement is based on water at exactly 4°C for accurate conversion
Use this converter primarily for low-pressure scenarios as centipascal measures very small pressures
Check your input for correctness to avoid conversion errors
Apply the conversion in hydraulic engineering, environmental monitoring, and fluid dynamics contexts for best results

Limitations

Conversion assumes the water temperature is 4°C; deviations may influence accuracy
Centipascal units reflect very small pressures and may not suit high-pressure measurements
Variations in fluid density other than pure water at 4°C are not accounted for
