What does 1 hectopascal represent?

1 hectopascal (hPa) equals 100 pascals and is often used to describe atmospheric pressure around sea level, being numerically identical to the millibar.

When is the terapascal unit used?

The terapascal (TPa) is used to quantify extremely high pressures found in high-pressure physics experiments, planetary interiors, and theoretical material science calculations.

Why are converted values from hPa to TPa very small?

Because the terapascal is a much larger unit—equal to one trillion pascals—converting everyday atmospheric pressures measured in hectopascal results in very small decimal numbers.
