What is a nanopascal?

A nanopascal (nPa) is an SI derived unit of pressure equal to one billionth (10⁻⁹) of a pascal, used for measuring very low pressures.

What does inch mercury (32°F) measure?

Inch mercury (32°F) is a manometric unit indicating the pressure exerted by a mercury column one inch high at 32°F, commonly used in meteorology and vacuum systems.

Why convert nanopascals to inch mercury?

Converting from nanopascals to inch mercury helps translate extremely small pressure values into widely used practical units for atmospheric, vacuum, or engineering applications.
