mbar to PSI Calculator: Convert Millibar to Pounds per Square Inch
Convert millibar (mbar) to pounds per square inch (PSI) with ease using our mbar to PSI calculator. This tool helps you quickly determine the equivalent pressure in PSI based on the mbar value entered.
Understanding mbar to PSI Conversion
Millibar (mbar) and pounds per square inch (PSI) are both units of pressure, but they are used in different measurement systems. PSI is used in the imperial system, while mbar is used in the metric system. Millibar is a commonly used unit in meteorology, while PSI is widely used in industrial applications. The ability to convert between these units is crucial for professionals working across systems that use different pressure measurements.
Conversion Factor
The conversion factor between millibar (mbar) and pounds per square inch (PSI) is that 1 mbar is equal to approximately 0.0145038 PSI.
| Unit | Symbol | Equivalent |
|---|---|---|
| Millibar | mbar | 1 mbar = 0.0145038 PSI |
| Pounds per Square Inch | PSI | 1 PSI = 68.9476 mbar |
Formula for mbar to PSI Conversion
The formula to convert millibar (mbar) to pounds per square inch (PSI) is:
PSI = mbar × 0.0145038
Where:
- mbar: Millibar
- PSI: Pounds per square inch (the result)
Common Applications of mbar to PSI Conversion

Frequently Asked Questions
What is the relationship between mbar and PSI?
Millibar (mbar) is a metric unit of pressure used mainly in weather forecasting, while PSI (pounds per square inch) is used in the imperial system. The relationship between the two is that 1 mbar is equal to 0.0145038 PSI.
How do I convert mbar to PSI?
To convert millibar (mbar) to pounds per square inch (PSI), multiply the mbar value by 0.0145038.
Why is mbar used instead of PSI in some regions?
Millibar is commonly used in meteorology and atmospheric pressure measurements, particularly in countries using the metric system. PSI is more commonly used in industrial, mechanical, and automotive applications, particularly in countries using the imperial system.
Can I use this calculator for atmospheric pressure measurements?
Yes! This calculator is ideal for converting atmospheric pressure, which is commonly measured in millibars, to PSI for use in applications where imperial units are required.
