What is the standard atmosphere unit used for?

Standard atmosphere is used as a reference pressure in chemical thermodynamics, laboratory gas pressures, and for describing pressures related to diving and engineering.

Why convert from standard atmosphere to millipascal?

Converting to millipascal allows expressing large conventional pressure values in smaller units suited for high-precision scientific instruments and sensitive measurements.

Are millipascal values always practical for everyday pressure measurements?

No, millipascal units produce very large numbers for atmospheric pressures and are mainly suited for precision contexts, not routine pressure measurements.
