gigapascal to pascal – How to convert GPa to Pa
Switching from gigapascal to pascal is a vital calculation in engineering, physics, and materials science. Gigapascal (GPa) measures extremely high pressures, while the pascal (Pa) is the SI base unit of pressure. Converting between them ensures accuracy in everything from industrial testing to nanotechnology research. Jetcalculator provides a quick converter, but let’s explore what these units mean, their formulas, and why they matter.
What is a Gigapascal (GPa)?
A gigapascal (GPa) is a very large unit of pressure equal to 1,000,000,000 Pa. It is often used to describe the strength of materials, geophysical forces, and high-pressure experiments. For instance, the hardness of diamond is around 60–100 GPa.
What is a Pascal (Pa)?
The pascal (Pa) is the SI unit of pressure, defined as one newton per square meter (N/m²). It is widely used in engineering, meteorology, and physics. However, since 1 Pa is very small, kilopascals (kPa), megapascals (MPa), and gigapascals (GPa) are often used for practicality.
Formula to Convert GPa to Pa
The relationship is straightforward:
-
1 GPa = 1,000,000,000 Pa -
1 Pa = 1 × 10⁻⁹ GPa
So the formulas are:
-
P (Pa) = P (GPa) × 1,000,000,000 -
P (GPa) = P (Pa) ÷ 1,000,000,000
Example: 3.5 GPa = 3,500,000,000 Pa.

Did you know?
-
Gigapascal fact: Earth’s inner core experiences pressures of around 360 GPa, far beyond what we experience at the surface.
-
Pascal fact: Atmospheric pressure at sea level is about 101,325 Pa, or just over 0.0001 GPa.
-
Gigapascal fact: Diamonds can withstand indentation pressures of 60–100 GPa, making them the hardest natural material known.
-
Pascal fact: The pascal is named after Blaise Pascal, a French mathematician and physicist who studied fluids and pressure in the 17th century.
Diamonds Under Pressure: A Gigapascal Story
One of the most famous real-world uses of gigapascal measurements is in studying diamonds. Diamonds are renowned for their hardness, and scientists measure this property in gigapascals. On the Vickers hardness scale, diamonds can resist indentation pressures up to 100 GPa.
To put this into perspective, normal atmospheric pressure is about 101,325 Pa. That means a diamond’s hardness is nearly one billion times greater than the air pressure around us. This incredible property not only makes diamonds valuable as gemstones but also as industrial tools. They are used in drilling, cutting, and high-tech applications where no other material can withstand such stress.
By converting from GPa to Pa, scientists and engineers can compare diamond hardness with other materials like steel (~1 GPa) or ceramics (~20 GPa). Without precise conversions, these comparisons would be impossible, and industries from mining to electronics would lack the standards they rely on.
Precision at Every Scale
The conversion 1 GPa = 1,000,000,000 Pa highlights the huge range of pressures science and engineering must account for. From the crushing forces inside Earth’s core to the hardness of diamonds, understanding the link between gigapascal to pascal keeps research and industry precise.
