Formula: Bar = Megapascal × 10
Multiply any megapascal value by 10 to get bar.
Reverse: Megapascal = Bar × 0.1

Use 10 as a quick mental multiplier.
Multiply result by 0.1 to recover the original MPa value.
Specifies concrete compressive strength (20–50 MPa) and steel yield strength (250–550 MPa).
Measures tensile strength, hardness, and fracture toughness in MPa.
Designs high-pressure hydraulic systems (20–35 MPa) for heavy machinery.
Calculates rock strength and in-situ stress states in MPa.
Specifies wellbore pressure, reservoir pressure, and fracture gradients in MPa.
Sets cutting pressure (200–600 MPa) for precision cutting applications.
The megapascal (MPa) equals 1,000,000 pascals (1,000 kPa) and is the standard unit for high-pressure engineering applications including hydraulics, structural materials, and industrial processes.
Steel has a tensile strength of about 400–550 MPa; concrete compressive strength is typically 20–40 MPa. Hydraulic systems in heavy machinery operate at 20–35 MPa. Water jet cutting uses pressures up to 600 MPa.
Interesting fact: The deepest point in the ocean (Mariana Trench, ~11,000 m) has a pressure of about 110 MPa — over 1,000 times atmospheric pressure.
The bar is a metric unit of pressure equal to exactly 100,000 pascals — very close to standard atmospheric pressure (1 atm = 1.01325 bar). It was introduced in 1909 and is widely used in Europe for weather forecasting, diving, and industrial applications.
Scuba diving cylinders are filled to 200–300 bar. Automotive tire pressure gauges often display in bar across Europe. Industrial compressors and hydraulic systems are commonly rated in bar.
Interesting fact: The millibar (mbar = hPa) is the standard unit for atmospheric pressure in meteorology worldwide. Standard sea-level atmospheric pressure is 1013.25 mbar.
Converting megapascal to bar is a common task in engineering, medicine, meteorology, and science. Different industries and countries use different pressure units — PSI in the US, bar in Europe, mmHg in medicine, and pascals in physics — making accurate conversion essential for cross-disciplinary work.
Quick reference: 5 MPa = 50 bar and 10 MPa = 100 bar. For the reverse: 1 bar = 0.1 MPa. The exact factor is 1 MPa = 10 bar.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
