To convert from hectopascal (hPa) to megapascal (MPa), use the following formula:
Let's convert 5 hectopascal (hPa) to megapascal (MPa).
Using the formula:
Therefore, 5 hectopascal (hPa) is equal to megapascal (MPa).

A hectopascal (hPa) is a metric unit used to measure pressure.
You will most commonly see it in weather reports to describe atmospheric pressure (also known as barometric pressure).
If you've seen millibars (mbar) on older weather maps, the hectopascal is its modern replacement.
The switch was simple for meteorologists because the units are exactly the same (1 hPa = 1 mbar).
The hectopascal is now the international standard for measuring atmospheric pressure, making weather data consistent worldwide.
The conversion is in the name. The prefix "hecto-" means 100. This makes the math simple:
Just as "hecto-" means 100, "kilo-" means 1,000. This defines their relationship:
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.
