What does 1 centimeter mercury (0°C) represent?

It is the pressure exerted by a 1-centimetre column of mercury at 0 °C under standard gravity conditions.

Why is kilopascal used as a unit for pressure?

Kilopascal is a derived SI unit that quantifies pressure as force per unit area and is suitable for everyday pressure ranges.

When should I consider corrections in this conversion?

Corrections are needed if mercury temperature or gravity conditions deviate from the standard 0 °C and 9.80665 m/s².
