What does 1 hectopascal equal in centimeter water (4°C)?

1 hectopascal is equal to approximately 1.0197 centimeter water at 4 degrees Celsius.

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

It is used to measure small pressures such as airway and ventilator pressures in respiratory care.

Can I use this converter for very high-pressure values?

The converter is more suitable for small pressure values as large pressures may not be practical to convert.

Common Use Cases

Interpreting atmospheric surface pressure in units suitable for small differences
Adjusting altimeter and flight planning settings in aviation
Monitoring airway and ventilator pressures during respiratory care
Calibrating medical devices and lab sensors requiring low-pressure units

Tips & Best Practices

Use this conversion primarily for small pressure values to ensure practical results
Consider the temperature dependency of the centimeter water unit defined at 4°C when interpreting results
Verify unit acceptance in scientific contexts as centimeter water is a non-SI unit

Limitations

Centimeter water is defined at 4°C and pressures may vary with temperature deviations
Conversion works best for low pressure values and might be impractical for very high pressures
Non-SI nature of centimeter water may limit its acceptance in some scientific applications
