What does one kilopascal represent?

One kilopascal is equal to 1,000 pascals and measures pressure as force per unit area, commonly used in engineering and meteorology.

Why is foot water measured at 4°C?

Foot water at 4°C is used because water has a reference density at this temperature, allowing consistent pressure measurements based on water column height.

Can this conversion be used for fluids other than water?

This conversion is primarily valid for hydrostatic pressures involving pure water at 4°C; other fluids may require different conversions.

What Is This Tool?

This converter changes pressure values from kilopascals (kPa), a widely used SI unit, to foot water (4°C) (ftAq), a unit representing the hydrostatic pressure of a water column at 4°C. It's useful in fields related to hydraulic engineering, fluid mechanics, and water resource management.

How to Use This Tool?

Enter the pressure value in kilopascals (kPa) into the input field.
Select kilopascal as the input unit and foot water (4°C) as the output unit.
Click the convert button to get the equivalent pressure in foot water (4°C) [ftAq].
Use the result to interpret pressure-related parameters in fluid or hydraulic applications.

Key Features

Converts pressure values from kilopascal [kPa] to foot water (4°C) [ftAq]
Supports understanding of hydraulic head and low-pressure measurements
Browser-based and easy to use for engineers and technicians
Provides clarity on pressure unit relationships commonly used in HVAC, pumping, and groundwater analysis

Examples

5 kPa converts to approximately 1.6728 ftAq by multiplying 5 by 0.3345622922.
10 kPa equals about 3.3456 ftAq using the conversion factor 0.3345622922.
Quick conversions assist in translating pressures from general engineering units to water column head.

Common Use Cases

Reading and interpreting manometer or gauge pressures in lab and field tests.
Designing and analyzing HVAC and hydraulic systems where pressure heads are expressed in feet of water.
Monitoring groundwater depth-pressure relationships and static head in wells.
Calculating pump heads and water-distribution system pressures in fluid mechanics.

Tips & Best Practices

Always confirm the water temperature is near 4°C to ensure the foot water unit applies accurately.
Use this converter for hydrostatic pressure scenarios rather than high-pressure or non-water fluids.
Verify input values and units carefully to avoid conversion errors.
Understand that actual conditions such as water composition and temperature may affect readings.

Limitations

The foot water unit assumes pure water at 4°C; deviations can impact results.
Not suitable for very high pressure or fluids other than water under hydrostatic conditions.
Conversion accuracy can be influenced by rounding errors in practical uses.
