To convert from pascal (Pa) to megapascal (MPa), use the following formula:
Let's convert 5 pascal (Pa) to megapascal (MPa).
Using the formula:
Therefore, 5 pascal (Pa) is equal to megapascal (MPa).
Here are some quick reference conversions from pascal (Pa) to megapascal (MPa):

A pascal (Pa) is the standard unit of pressure in the International System of Units (SI). It is a derived unit, meaning other base units define it.
The primary pascal definition is one newton of force applied over an area of one square meter (1 Pa = 1 N/m2).
Because a single pascal represents a very small amount of pressure, it is most often seen in multiples.
The most common multiples are the kilopascal (kPa), equal to 1,000 pascals, and the megapascal (MPa), equal to 1,000,000 pascals.
These units are widely used in fields from weather forecasting to material science.
The pascal (Pa) unit is named in honor of Blaise Pascal, a key 17th-century French mathematician, physicist, and inventor.
His groundbreaking work on how fluids behave under pressure (known as hydrodynamics and hydrostatics) and his formulation of Pascal's Law were essential to our modern understanding of pressure.
To understand just how small a single pascal is, here are two real-world examples:
This shows why, for most everyday measurements (like tire pressure or weather), the larger kilopascal (kPa) is much more practical.
If you've ever looked at engineering specifications, construction materials, or high-pressure equipment, you've likely seen the term 'MPa.'
A megapascal (MPa) is a unit of pressure in the metric system, equal to one thousand kilopascals (1000 kPa).
The plural form is megapascals.
The megapascal (MPa) is a fundamental unit for quantifying the strength of materials in engineering and construction.
It is commonly used to express a material's ultimate tensile strength (the maximum stress it can withstand while being pulled apart) and compressive strength (its resistance to being squeezed).
For example, structural steel might have a tensile strength of 400 MPa. In comparison, high-performance concrete can have a compressive strength exceeding 80 MPa.
Understanding how to convert megapascals to other pressure units is crucial for global applications.
Here are the most common conversions:
The pound per square inch (PSI) is a unit commonly used in the United States for measuring tire pressure and hydraulic systems.
The bar is a unit often used in Europe for weather forecasting and scuba diving.
Megapascals are used to describe immense pressures found in both natural and industrial settings.
The water pressure at the bottom of the Mariana Trench, the deepest point in the ocean, is about 108.6 MPa.
In industry, a high-pressure waterjet cutter operates at pressures ranging from 200 to 600 MPa, demonstrating enough force to slice through metal and stone.
