What is an inch water (4°C) unit?

An inch water (4°C) is a pressure unit representing the pressure exerted by a 1-inch column of water at 4 degrees Celsius under standard gravity, used for measuring low pressures with fine resolution.

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

Converting to dekapascal allows easier comparison and calibration by using an SI-derived unit, which is widely recognized and used in scientific and engineering applications.

When might this conversion be necessary?

This conversion is essential in HVAC system diagnostics, audiology pressure measurements, cleanroom monitoring, and laboratory calibration of low-pressure sensors.
