Definition of MPa
Megapascal: High-Pressure Applications
The megapascal (MPa) is an SI-derived unit of pressure equal to 1,000,000 pascals (1,000 kPa or 10 bar). It is commonly used in engineering and materials science for measuring high pressures, such as the tensile strength of materials, hydraulic system pressures, and geological pressures. The megapascal provides convenient numbers when dealing with pressures that would be unwieldy in pascals or kilopascals.
Conversions to Other Units of Measurement:
- Bar: 1 megapascal equals exactly 10 bar. This simple relationship makes MPa convenient for high-pressure industrial work. For example, 20 MPa equals 200 bar.
- PSI: 1 megapascal equals approximately 145.038 psi. This conversion is essential for engineering specifications. For example, a steel with 250 MPa yield strength equals approximately 36,260 psi.
- Kilopascal (kPa): 1 megapascal equals exactly 1,000 kPa. For example, 5 MPa equals 5,000 kPa.
- Pascal (Pa): 1 megapascal equals exactly 1,000,000 pascals. This is the fundamental SI relationship.
- Atmosphere (atm): 1 megapascal equals approximately 9.86923 atm. This shows that MPa represents significantly higher pressures than atmospheric.
The megapascal is essential in structural engineering, material science, and any application involving high pressures.

About the MPa
Facts & Uses
- 1 MPa = 1,000,000 Pa = 1 N/mm² exactly — the convenient unit for high pressures and material stresses.
- Standard in materials science for tensile strength: structural steel ≈ 250 MPa yield, high-strength steel 400-700 MPa, carbon fiber 3500+ MPa.
- Used in hydraulic systems (typical hydraulic pressures 10-35 MPa), injection molding, and industrial pressure vessels.
- High-pressure applications: diamond anvil cells reach 100-300 GPa; deep ocean trenches around 100 MPa at the Mariana Trench.
Curiosities
- Concrete compressive strength is typically expressed in MPa: 25 MPa for residential, 40+ MPa for high-rise buildings, 100+ MPa for ultra-high-performance concrete.
- The Earth's pressure at the core-mantle boundary reaches about 136 GPa = 136,000 MPa — beyond what can be sustained at the surface in any container.
- 1 MPa is approximately the pressure under a 1 cm column of mercury per square millimeter, or about 145 psi.
- Approximate equivalents: 1 MPa = 145 psi = 9.87 atm = 10 bar.
