Why does the inch mercury use 60°F as a reference temperature?

The 60°F reference fixes mercury density to provide consistent calibration and reporting for atmospheric and instrument pressures.

What is the significance of the millimeter mercury being defined at 0°C?

Using 0°C as the reference temperature standardizes the mercury density, making mmHg widely accepted for clinical and laboratory pressure measurements.

Can this conversion be used for all pressure measurements?

This conversion is suitable where inch mercury (60°F) and millimeter mercury (0°C) units are applicable, such as meteorology, aviation, medical, and engineering fields, but be cautious of temperature-related discrepancies.
