What does inch mercury (32°F) measure?

It is a manometric unit of pressure defined as the pressure from a one-inch mercury column at 32°F under standard gravity.

Why convert inch mercury to kilonewton per square meter?

Converting to kN/m² allows expressing pressure in standardized SI units useful in engineering and scientific calculations.

Can I use this conversion for temperatures other than 32°F?

The inch mercury unit is temperature dependent; using other temperatures can affect conversion accuracy.
