Frequently asked questions
What is the source unit in this conversion?
The source unit is the hectopascal (hPa). Hectopascal is 100 pascal units.
What is the destination unit in this conversion?
The destination unit is the gigapascal (GPa). Gigapascal is 1000000000 pascal units.
How do I convert hectopascal to gigapascal?
Multiply the hectopascal value by 1.000000e-07. For example, 10 hPa × 1.000000e-07 = 0.000001 GPa.
Is the hectopascal to gigapascal conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in hectopascal needs to be compared with, or reported in, gigapascal, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert gigapascal back to hectopascal?
Yes. Multiply the gigapascal value by 1.000000e+07 to get hectopascal.

About this conversion
This page converts hectopascal (hPa) to gigapascal (GPa) within the pressure converter.
Hectopascal is 100 pascal units. Gigapascal is 1000000000 pascal units.
The formula is gigapascal = hectopascal × 1.000000e-07, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
Use the calculator above for instant results, or the table below for common hectopascal values already converted to gigapascal.
