What is an attopascal used for?

It is used to quantify extremely low pressures, such as those found in astrophysics, ultra-high vacuum systems, and theoretical computations.

Why convert attopascal to poundal/square foot?

To translate very small SI pressure units into the FPS system for comparison with historical data or engineering applications using legacy units.

Are values from this conversion practical for everyday engineering?

Often, converted values are very small and might be below detection limits or practical use in many engineering scenarios.
