What does one millimeter mercury (0°C) represent?

It is the pressure exerted by a 1 mm column of mercury at 0°C under standard gravity, commonly abbreviated as mmHg.

Why use kilopascal instead of millimeter mercury for pressure?

Kilopascal is an SI derived unit suitable for engineering and meteorology, providing standardization and compatibility with international measurements.

Can I use this conversion for all pressure measurements?

While useful for many clinical and engineering contexts, this conversion is less suitable when exact fluid dynamics precision is needed or when conditions vary from the mmHg standard.
