Why does the conversion depend on temperature?

Water density varies with temperature, so pressure units based on water columns at different temperatures (4°C vs 60°F) require conversion to account for these density changes.

Can this converter be used for gas pressure measurements?

No, this conversion is specific to pressures derived from hydrostatic water columns and is not suitable for gases or other fluids.

What industries commonly use this conversion?

It's widely used in plumbing, water resource management, HVAC system design, gas regulation, laboratory fluid instrumentation, and groundwater environmental monitoring.

What Is This Tool?

This tool converts pressure values from foot water (4°C), a unit representing hydrostatic pressure exerted by a 1-foot column of water at 4°C, to inch water (60°F), which expresses pressure from a 1-inch water column at 60°F. It's designed to assist with accurate conversions reflecting temperature-dependent water densities.

How to Use This Tool?

Enter the pressure value in foot water (4°C)
Select foot water (4°C) as the input unit
Select inch water (60°F) as the output unit
Click the convert button to get the equivalent pressure in inch water (60°F)

Key Features

Converts pressure from foot water (4°C) to inch water (60°F)
Accounts for temperature-specific water densities
Useful for low-pressure and hydraulic head measurements
Supports applications in HVAC, gas regulation, and groundwater monitoring
Browser-based and easy to use

Examples

2 foot water (4°C) converts to approximately 24.023 inch water (60°F)
0.5 foot water (4°C) equals about 6.006 inch water (60°F)

Common Use Cases

Specifying hydraulic head pressures for pumps and water systems
Interpreting manometer and gauge readings in laboratories and HVAC
Measuring duct and filter pressure drops in ventilation systems
Setting residential gas service pressures and regulators

Tips & Best Practices

Ensure stable temperature conditions to improve accuracy
Use calibrated instruments for precise pressure measurements
Apply this conversion only for pressures derived from water columns
Consider temperature effects when interpreting converted values

Limitations

Conversion depends on water density differences at 4°C vs 60°F
Only applicable to pressures from hydrostatic water columns, not gases or other fluids
Measurement accuracy depends on instrument calibration and temperature stability

Key Terminology

Foot water (4°C) [ftAq]: A pressure unit equal to the hydrostatic pressure exerted by a 1-foot column of pure water at 4°C, commonly used as a reference density.
Inch water (60°F) [inAq]: A pressure unit representing the hydrostatic pressure exerted by a 1-inch column of water at 60°F, used to measure very small pressure differences.
Hydrostatic Pressure: Pressure exerted by a fluid at rest due to the force of gravity, often expressed using the height of a fluid column.
