What does centipascal (cPa) measure?

Centipascal is an SI-derived unit of pressure equivalent to one hundredth of a pascal, used to express very small pressures or pressure differences.

Why use millimeter water (4°C) as a pressure unit?

Millimeter water (4°C) measures hydrostatic pressure exerted by a 1 mm water column at 4°C and is commonly used in low-pressure fluidic, HVAC, and laboratory applications.

How accurate is the conversion between cPa and millimeter water (4°C)?

The conversion assumes standard gravity and water density at 4°C; variations in these conditions or sensor precision can affect accuracy.
