Convert hectopascal to exapascal
Please provide values below to convert hectopascal [hPa] to exapascal [EPa], or Convert exapascal to hectopascal.
How to Convert Hectopascal to Exapascal
1 hPa = 1e-16 EPa
Example: convert 15 hPa to EPa:
15 hPa = 15 × 1e-16 EPa = 1.5e-15 EPa

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.
Exapascal
An exapascal (EPa) is a unit of pressure equal to 10^18 pascals, used to measure extremely high pressures.
History/Origin
The exapascal was introduced as part of the International System of Units (SI) prefixes to represent very large pressure values, primarily in scientific and engineering contexts involving high-pressure phenomena.
Current Use
The exapascal is mainly used in fields such as geophysics, astrophysics, and high-pressure physics to describe immense pressures found in planetary interiors, stellar environments, and experimental high-pressure research.
