Why is the inch mercury measurement fixed at 60°F?

The 60°F reference ensures consistent mercury density for accurate pressure calibration and reporting.

What applications use micropascal as a pressure unit?

Micropascal is commonly used in acoustic pressure measurements like human hearing references, underwater acoustics, and sensitive microphone calibration.

Can I use this conversion for general atmospheric pressure readings?

While possible, micropascal units are more suited for very small pressure variations rather than typical atmospheric measurements.
