What is foot water (4°C) used for?

Foot water (4°C) quantifies hydrostatic pressure exerted by a 1-foot column of water at 4°C, commonly used in hydraulic head, pump specifications, and groundwater pressure measurements.

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

Centimeter water (4°C) is used to express small pressures like airway or ventilator pressures and settings for devices such as chest drains and CPAP equipment.

Can I use this converter for pressures at temperatures other than 4°C?

This conversion assumes the water is at exactly 4°C; variations in temperature or water density can lead to less accurate conversions.

What Is This Tool?

This converter allows you to transform pressure measurements expressed in foot water (4°C) into centimeter water (4°C), two units linked to the hydrostatic pressure exerted by water columns at 4°C. It helps bridge measurements relevant in hydraulic, medical, and laboratory fields.

How to Use This Tool?

Enter the value in foot water (4°C) units you want to convert.
Select foot water (4°C) as the original unit and centimeter water (4°C) as the target unit.
Submit to get the corresponding value in centimeter water (4°C).

Key Features

Converts low-pressure units based on water density at 4°C.
Uses defined conversion factor from foot water to centimeter water.
Supported in contexts like hydraulic head, respiratory care, and lab instrumentation.

Examples

2 foot water (4°C) converts to approximately 60.96 centimeter water (4°C).
0.5 foot water (4°C) converts to about 15.24 centimeter water (4°C).

Common Use Cases

Translating hydraulic head and low-pressure values in water distribution systems.
Interpreting manometer and gauge readings in HVAC and fluid instrumentation.
Reporting pressures in respiratory equipment and medical device settings.
Measuring static head in groundwater and well pressure assessments.

Tips & Best Practices

Verify water temperature is at 4°C for accurate pressure reference.
Use the converter for low-pressure ranges where these units apply.
Be cautious converting to SI units since centimeter water is a non-SI unit.

Limitations

Conversion accuracy depends on water being exactly at 4°C.
Not suitable for high-pressure measurements outside low-pressure scope.
Centimeter water is non-SI, requiring extra steps for SI compatibility.
