Why is inch mercury measured at 32°F?

Inch mercury (inHg) is defined at 32°F because this temperature corresponds to mercury’s standard density used for consistent pressure measurement under standard gravity.

What does kilogram-force per square meter represent?

Kilogram-force per square meter (kgf/m²) represents pressure as the force of one kilogram-force applied uniformly over one square meter area, commonly used in legacy and engineering contexts.

Can I use this tool for aviation pressure conversions?

Yes, this tool helps convert pressure readings from inch mercury used in altimeter settings to kilogram-force per square meter, useful for applications requiring legacy unit translation.
