A pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter, used to measure pressure and mechanical stress in various fields.

What does a centimeter water (4°C) measure?

A centimeter water (4°C) represents the pressure from a column of water 1 cm high at 4°C and is used for small pressure measurements in medical and lab contexts.

Why is temperature important for centimeter water units?

Because the unit is based on water density at 4°C, variations in temperature can affect the pressure value represented by a centimeter water.
