What does 1 millibar represent?

One millibar equals 100 pascals and is widely used in meteorology to express atmospheric pressure.

What is foot water (60°F) used for?

Foot water at 60°F measures hydrostatic pressure from a 1-foot column of water at that temperature, common in HVAC and fluid systems.

Why is it important to consider temperature when using foot water pressure?

Because water density changes with temperature, the foot water pressure unit is accurate only at around 60°F under standard gravity.

What Is This Tool?

This tool allows users to convert pressure measurements from millibar (mbar), a standard atmospheric pressure unit, into foot water at 60°F (ftAq), a hydrostatic pressure unit used for low-pressure and fluid head calculations.

How to Use This Tool?

Enter the pressure value in millibar (mbar) you want to convert.
Select the output unit as foot water (60°F) [ftAq].
Click the convert button to see the equivalent pressure value in ftAq.

Key Features

Converts millibar to foot water (60°F) with accuracy based on standardized definitions.
Browser-based and easy to use with no installation required.
Suitable for meteorology, HVAC, gas regulation, and laboratory applications.

Examples

100 millibar equals approximately 3.3488 foot water (60°F).
500 millibar equals about 16.7442 foot water (60°F).

Common Use Cases

Weather forecasting and atmospheric pressure analysis using millibar values.
Measuring low-pressure differences in HVAC systems with foot water units.
Monitoring pressure drops in pumps, water filters, and laboratory manometers.

Tips & Best Practices

Ensure water temperature is approximately 60°F when interpreting foot water pressure.
Use this conversion for low-pressure and hydrostatic pressure measurements.
Apply the millibar unit for general atmospheric pressure and foot water for head-related measurements.

Limitations

Foot water pressure depends on water density which varies with temperature.
Conversion accuracy assumes water at 60°F under standard gravity.
Millibar represents general atmospheric pressure, so differences exist in some specialized hydrostatic contexts.
