What is the hectopascal unit used for?

Hectopascal is widely used in meteorology and atmospheric science to represent air pressure, including weather reports and flight planning.

How does the standard atmosphere unit relate to real-world pressure?

The standard atmosphere represents an average atmospheric pressure at sea level, serving as a reference in scientific, engineering, and diving contexts.

Can this converter be used for high-precision laboratory measurements?

While useful, hectopascal to standard atmosphere conversions may need more precise methods for laboratory or specialized engineering applications.
