What does inch mercury (32°F) measure?

It is a manometric pressure unit defined by the pressure exerted by a one-inch column of mercury at 32°F under standard gravity.

Where is foot water (4°C) used?

Foot water (4°C) is used to express low pressures or hydraulic head based on the pressure from one foot column of water at 4°C.

Can this converter be used for measurements outside the standard temperatures?

This conversion tool assumes standard temperatures; using it outside these conditions may reduce accuracy.

Click the convert button to receive the corresponding pressure in foot water units.

Key Features

Converts pressure units from inch mercury (32°F) to foot water (4°C) accurately based on defined conversion rates.
Browser-based and easy to use with straightforward input and output.
Supports practical applications in meteorology, aviation, HVAC, hydraulic engineering, and groundwater studies.

Examples

5 inHg multiplied by 1.1329550549 equals approximately 5.6648 ftAq.
10 inHg multiplied by 1.1329550549 equals approximately 11.3296 ftAq.

Common Use Cases

Translating atmospheric or vacuum pressure readings from mercury columns to water columns in meteorology and aviation.
Interpreting hydraulic head and low-pressure measurements in water-distribution and pumping systems.
Converting manometer and gauge pressures for laboratory, HVAC, or fluid instrumentation analyses.
Relating static head or depth-pressure data in groundwater and well monitoring.

Tips & Best Practices

Always ensure input values are at standard temperature conditions (32°F for mercury and 4°C for water) for accurate conversion.
Use this converter for static pressure contexts to maintain validity of results.
Double-check units when interpreting readings in different disciplines such as HVAC or hydraulic engineering.

Limitations

The conversion assumes standard temperature conditions and fluid densities; deviations can affect precision.
It is intended for static pressure situations and may not represent dynamic or fluctuating pressures accurately.
