What is the relationship between pascal and hectopascal?

One pascal equals 0.01 hectopascal, meaning one hectopascal is equivalent to 100 pascals.

Why convert pascals to hectopascals?

Converting to hectopascals is common in meteorology and aviation because it aligns with standard units used for air pressure reporting, altimeter settings, and sensor calibration.

Where is this conversion most commonly applied?

This conversion is frequently used in meteorology for weather forecasts, aviation for flight planning, and atmospheric science for sensor calibration.
