Why is inch mercury measured at 60°F?

The 60°F reference temperature fixes mercury density to ensure consistent pressure calibration and reporting.

What does one megapascal represent?

One megapascal equals one million pascals and quantifies high pressure or mechanical stress in scientific fields.

Where is inch mercury commonly used?

Inch mercury is used in meteorology for atmospheric pressure, aviation for altimeter settings, and laboratory vacuum measurements.
