What is the relationship between micropascal and nanopascal?

One micropascal (µPa) is equal to one thousand nanopascals (nPa), based on their respective definitions as 10⁻⁶ pascal and 10⁻⁹ pascal.

Where are micropascals typically used?

Micropascals are commonly used for measuring acoustic pressure levels, such as reference sound pressure for human hearing and underwater acoustics.
