How to use it
- Type the value in the bar box.
- Read the result in megapascals as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
MPa = bar × 0.1
Multiply the value in bar by 0.1 to get megapascals.
Example
To convert 25 bar to megapascals: 25 × 0.1 = 2.5 MPa.

About the units
- Bar
- A metric unit equal to exactly 100,000 pascals, close to atmospheric pressure at sea level.
- Megapascal
- Exactly one million pascals, used for concrete and steel strength and hydraulics. It equals one newton per square millimeter.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many megapascals are in one bar?
1 bar = 0.1 MPa exactly.
How do I convert bar to megapascals?
Use MPa = bar × 0.1. For example, 25 bar = 2.5 MPa.
How many bar are in one megapascal?
1 MPa = 10 bar.
What is the difference between gauge and absolute pressure?
Gauge pressure is measured from the surrounding air pressure, while absolute pressure starts from a perfect vacuum. These converters change the unit only, so a gauge reading stays a gauge reading.
Are torr and mmHg the same?
Almost. One torr is 101325/760 Pa, about 133.322368 Pa, and one conventional mmHg is 133.322387 Pa, a difference of less than one part per million. For everyday use you can treat them as equal.
