What is a centimeter water (4°C)?

It is a non-SI unit of pressure equal to the pressure from a 1 cm column of pure water at 4°C, used for measuring small pressures in medical and laboratory settings.

What does a gigapascal represent?

A gigapascal (GPa) is a unit of pressure or stress equal to one billion pascals, commonly used in engineering and materials science for very high pressures.

Why convert from centimeter water (4°C) to gigapascal?

To translate low-pressure measurements into a high-pressure scale used in engineering and materials science, enabling better comparisons and calculations.
