Convert hectopascal to gigapascal
Please provide values below to convert hectopascal [hPa] to gigapascal [GPa], or Convert gigapascal to hectopascal.
1 hPa = 1e-07 GPa. To convert hectopascal to gigapascal, multiply the value by 1e-07; to go the other way, divide by it (1 GPa = 10000000 hPa). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 hPa = 1e-07 GPa
- 1 GPa = 10000000 hPa
- 10 hPa = 1e-06 GPa
- 100 hPa = 1e-05 GPa
How to Convert Hectopascal to Gigapascal
1 hPa = 1e-07 GPa
Example: convert 15 hPa to GPa:
15 hPa = 15 × 1e-07 GPa = 1.5e-06 GPa

Hectopascal
The hectopascal (hPa) is a unit of pressure equal to 100 pascals, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The hectopascal was introduced as part of the metric system and became widely adopted in meteorology during the 20th century for standardizing atmospheric pressure measurements.
Current Use
Today, the hectopascal is predominantly used in weather reporting and forecasting to indicate atmospheric pressure, with standard sea-level pressure approximately 1013 hPa.
Gigapascal
A gigapascal (GPa) is a unit of pressure equal to one billion pascals, where one pascal (Pa) is the force of one newton per square meter.
History/Origin
The gigapascal was introduced as part of the International System of Units (SI) to measure high-pressure phenomena, especially in materials science and geophysics, as a larger unit than the pascal for convenience.
Current Use
GPa is commonly used to quantify stress, pressure in geological formations, material strength, and high-pressure physics applications.
Frequently Asked Questions
What is 1 hectopascal in gigapascal?
1 hectopascal (hPa) = 1e-07 gigapascal (GPa).
How do you convert hectopascal to gigapascal?
Multiply the hectopascal value by 1e-07. For example, 25 hPa × 1e-07 = 2.5e-06 GPa.
What is 10 hectopascal in gigapascal?
10 hPa = 1e-06 GPa.
Which unit is larger, the hectopascal or the gigapascal?
The gigapascal is the larger unit: 1 hPa equals only 1e-07 GPa.
