A megapascal (MPa) is a unit of pressure that is commonly used in engineering and science.

What is MPa?

A megapascal (MPa) is a unit of pressure that is commonly used in engineering and science. One megapascal is equal to one million pascals, which is the single unit of pressure.

It is a unit of measurement that is part of the International System of Units (SI). The SI is the modern form of the metric system and is the most widely used system of measurement in the world.

To provide some context, one megapascal is approximately equal to the pressure exerted by a mass of about 100 metric tons resting on an area of one square meter. In practical terms, this means that hydraulic systems, which often operate at pressures of several hundred or even thousands of MPa, are capable of generating extremely high forces and are used in applications such as heavy construction, mining, and aerospace.

In the metric system, the megapascal is a commonly used unit of pressure, along with other units such as kilopascals (kPa), bar, and atmospheres (atm). In the United States and some other countries, the non-SI unit of pressure, pounds per square inch (psi), is often used instead.

Hydraulic hose standardisation:

Hydraulic hoses are governed by both industry and international standards – SAE Standards (set by Society of Automotive Engineers), and EN Standards – to ensure they comply with safety and performance standards.
