What does inch mercury (32°F) measure?

It measures pressure as the force exerted by a one-inch column of mercury at 32°F under standard gravity.

Where is centimeter water (4°C) commonly used?

It is often used to express small pressures in medical and laboratory environments, such as airway pressures in respiratory care.

Is the conversion affected by temperature changes?

Yes, the accuracy depends on the standard temperatures of 32°F for mercury and 4°C for water used for defining each unit.
