Megapascal vs Bar
What is Megapascal?
Megapascal (MPa) is a unit of pressure measurement. 1 megapascal is equal to 10.0000000 bar.
The Bar in Engineering
Bar (bar) is a unit of pressure measurement. 1 bar is equal to 0.1000000 megapascal.
Pressure Units Across Industries
Pressure measurements vary dramatically by industry. Meteorologists report in millibars or hectopascals, tire shops use PSI, scuba divers think in atmospheres or bar, vacuum engineers work in torr, and hydraulic systems specify in megapascals. A single industrial plant might encounter all these units across different equipment manuals, safety datasheets, and regulatory standards from different countries.

How to Convert Megapascal to Bar?
We can convert megapascal to bar by using an example.
Example:
Convert 20 Megapascal to Bar?
We know 1 Megapascal = 10.0000000 bar; 1 Bar = 0.1000000 megapascal.
20 megapascal = ___bar
20 × 10.0000000 = 200.00000 bar (we know 1 megapascal = 10.0000000 bar)
Answer:
20 megapascal = 200.00000 bar
How to Convert MPa to Bar (Step-by-Step)
Converting megapascals to bar is common when reading hydraulic catalogs (Bosch Rexroth, Parker, Eaton) that list component ratings in MPa while plant gauges display bar. The relationship is exact: 1 MPa = 10 bar.
- Write down the pressure value in megapascals (MPa).
- Multiply the MPa value by 10.
- The result is the equivalent pressure in bar.
- Verify: since 1 bar = 0.1 MPa, your bar value should be 10× the MPa value.
Common MPa to Bar Conversions
Hydraulic system pressures and material catalog values converted from MPa to bar.

| 1 MPa | 10 bar |
| 7 MPa | 70 bar |
| 16 MPa | 160 bar |
| 21 MPa | 210 bar |
| 25 MPa | 250 bar |
| 31.5 MPa | 315 bar |
| 35 MPa | 350 bar |
| 70 MPa | 700 bar |
Solved Examples: MPa to Bar
Question 1: A hydraulic pump catalog lists maximum pressure as 28 MPa. What pressure gauge reading (in bar) corresponds to this limit?
Solution:
Pressure in bar = Pressure in MPa × 10
= 28 × 10
= 280 bar
Answer: 28 MPa = 280 bar — the system relief valve should be set just below this.
Question 2: A hydraulic cylinder is rated for 16 MPa working pressure. Express in bar.
Solution:
Pressure in bar = 16 × 10
= 160 bar
Answer: 16 MPa = 160 bar — standard for light-duty industrial cylinders.
Question 3: The burst pressure of a hydraulic hose is 105 MPa. Convert to bar.
Solution:
Pressure in bar = 105 × 10
= 1050 bar
Answer: 105 MPa = 1050 bar — with a 4:1 safety factor, working pressure is 262 bar.

Hydraulic Catalog Conventions: MPa vs Bar
Major hydraulic component manufacturers (Bosch Rexroth, Parker Hannifin, Eaton, Danfoss) publish technical data in MPa in international catalogs and bar in European field documentation. A Rexroth A10V pump rated at 28 MPa (280 bar) is the same product listed as 4000 PSI in US literature. When ordering replacement components internationally, confirming the pressure rating unit prevents selecting undersized parts that could fail catastrophically.
Hydraulic System Pressure Classes
Hydraulic systems are classified by operating pressure: low pressure 0.5-7 MPa (5-70 bar) for lubrication and pilot circuits; medium pressure 7-21 MPa (70-210 bar) for general industrial machinery; high pressure 21-35 MPa (210-350 bar) for excavators and presses; ultra-high pressure 35-100 MPa (350-1000 bar) for hydroforming and water-jet cutting. Component selection (seals, fittings, hoses) must match the pressure class.
Key Takeaways
- Multiply MPa by 10 to get bar (exact relationship: 1 MPa = 10 bar).
- Move the decimal one place right: 25 MPa = 250 bar.
- Hydraulic catalogs use MPa internationally and bar for field gauges.
- Standard industrial hydraulics: 16-35 MPa (160-350 bar).
- Hose burst ratings are typically 4× working pressure.
- Always match component ratings to the same unit before comparing.
Megapascal to Bar Conversion Formula
bar = megapascal × 10.0000000
1 megapascal = 10.0000000 bar
1 bar = 0.1000000 megapascal
Reverse: megapascal = bar × 0.1000000
