Definition of Pascal
Pascal: The SI Unit of Pressure
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter (N/m²). Named after the French mathematician and physicist Blaise Pascal, it is used extensively in scientific, engineering, and meteorological applications. The pascal is a relatively small unit, so larger multiples like kilopascal (kPa) and megapascal (MPa) are commonly used in practice.
Conversions to Other Units of Measurement:
- Bar: 1 pascal equals 0.00001 bar (or 1 bar = 100,000 Pa). This conversion is frequently used in industrial applications. For example, standard atmospheric pressure (101,325 Pa) equals approximately 1.01325 bar.
- PSI (Pound per Square Inch): 1 pascal equals approximately 0.000145038 psi. This conversion is essential for interfacing with equipment using imperial measurements. For example, 100,000 Pa equals approximately 14.5 psi.
- Atmosphere (atm): 1 pascal equals approximately 9.8692×10⁻⁶ atm. Standard atmospheric pressure is defined as exactly 101,325 Pa or 1 atm.
- Torr: 1 pascal equals approximately 0.00750062 torr. This conversion is commonly used in vacuum technology. For example, 133.322 Pa equals 1 torr.
- Millibar (mbar): 1 pascal equals 0.01 millibar. This conversion is frequently used in meteorology. For example, standard atmospheric pressure equals 1013.25 mbar.
The pascal is fundamental to pressure measurement, providing a standardized unit for scientific calculations and engineering specifications.

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 Pascal
Facts & Uses
- SI derived unit of pressure: 1 Pa = 1 N/m². Named after Blaise Pascal (1623-1662), the French mathematician and physicist.
- Universal in scientific publications, weather data (hectopascals on barometric charts), and engineering specifications.
- The pascal is a very small unit for everyday pressures — atmospheric pressure is ~101,325 Pa, so weather forecasts use hectopascals (hPa) or kilopascals (kPa).
- Used in fluid mechanics, vacuum measurements, materials science (stress and strain), and tire pressure in metric markets.
Curiosities
- The pascal was adopted as the SI unit of pressure at the 14th CGPM in 1971, replacing the older mechanical units like dyne/cm² (CGS) and lbf/in² (imperial).
- 1 Pa is roughly the pressure exerted by a thin layer of paper resting on a tabletop — about 0.0000099 atmospheres.
- The millibar (mbar), traditionally used in meteorology, equals exactly 1 hPa (100 Pa). Most modern weather services have switched to hPa for SI compatibility.
- Approximate equivalents: 1 Pa ≈ 0.000145 psi; 1 atm = 101,325 Pa = 1013.25 hPa = 14.696 psi.

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.
