What is a dekapascal used for?

Dekapascal (daPa) is primarily used for measuring small pressure differences such as in audiology, HVAC system monitoring, and laboratory calibration.

Why convert dekapascal to millimeter water (4°C)?

Converting to millimeter water (4°C) helps express pressure in a hydrostatic unit that is practical for measuring very small pressures in various applications like sensor calibration and cleanroom monitoring.

Are temperature and water purity important for this conversion?

Yes, the millimeter water unit depends on pure water at 4 °C and standard gravity, so deviations can affect conversion accuracy.
