Frequently Asked Questions
-
What does a millimeter water (4°C) measure?
-
It is the hydrostatic pressure exerted by a 1 mm column of pure water at 4 °C under standard gravity, used for small pressure measurements.
-
Why use centipascal [cPa] instead of pascal?
-
Centipascal is useful for expressing very small pressure differences by dividing pascals into smaller units for higher precision.
-
In which fields is this conversion commonly applied?
-
It is used in HVAC design, cleanroom pressure monitoring, microfluidics research, medical device calibration, and laboratory pressure measurements.
Key Terminology
-
Millimeter water (4°C)
-
A pressure unit based on the hydrostatic pressure of a 1 mm water column at 4 °C under standard gravity.
-
Centipascal [cPa]
-
An SI-derived pressure unit equal to one hundredth of a pascal, used for very small pressure differences.
