What Is This Tool?
This tool converts pressure values from millibar (mbar), a metric unit widely used in atmospheric sciences and weather reporting, to inch mercury (60°F) (inHg), an imperial unit commonly applied in U.S. aviation and barometric measurements. It facilitates seamless translation of pressure data between these units for easier interpretation and use.
How to Use This Tool?
-
Enter the pressure value in millibar (mbar) into the input field
-
Select inch mercury (60°F) (inHg) as the desired output unit
-
Click the convert button to see the pressure value converted to inch mercury (60°F)
-
Use the result for applications such as weather forecasting, altimeter setting, or vacuum system monitoring

Examples
-
Convert 1000 mbar to inch mercury (60°F): 1000 × 0.0296133971 = 29.6134 inHg
-
Convert 500 mbar to inch mercury (60°F): 500 × 0.0296133971 = 14.8067 inHg
Common Use Cases
-
Translating meteorological pressure readings from metric to imperial units
-
Setting altimeters in aviation using U.S. customary pressure units
-
Reading and calibrating barometers and weather station instruments
-
Monitoring vacuum levels in laboratory and industrial systems
Tips & Best Practices
-
Always ensure temperature considerations are accounted for due to mercury density at 60°F
-
Double-check unit selections to avoid misinterpretation, especially in aviation settings
-
Use this conversion tool as a part of instrument calibration workflows
-
Apply the tool to translate between units when sharing pressure data internationally
Limitations
-
Conversion depends on the mercury density fixed at 60°F, so temperature variations can affect accuracy
-
Differences between metric and imperial systems require careful application to prevent errors
-
Not suitable for converting pressure measurements outside the defined unit types
Frequently Asked Questions
-
What is a millibar used for?
-
A millibar is used to express air pressure, especially in meteorology and atmospheric sciences, and is commonly found in weather reports and aviation settings.
-
Why is a reference temperature of 60°F used for inch mercury?
-
The 60°F reference fixes mercury density for consistent calibration and accurate pressure measurements across different instruments.
-
Can I use this conversion for altimeter settings in aviation?
-
Yes, this conversion is frequently used in U.S. aviation for setting altimeters and referencing atmospheric pressure.
Key Terminology
-
Millibar (mbar)
-
A metric pressure unit equal to 100 pascals; widely used in atmospheric pressure measurement and aviation.
-
Inch mercury (60°F) (inHg)
-
An imperial pressure unit defined by the hydrostatic pressure of a one-inch column of mercury at 60°F used in barometric and aviation pressure readings.
-
Conversion Rate
-
The factor (0.0296133971) used to convert millibar values to inch mercury (60°F).
