What is a decipascal used for?

A decipascal measures very small pressure values, commonly used in acoustic sensor calibration, and low differential pressure measurements in labs and cleanrooms.

Why is inch water (4°C) used as a pressure unit?

Inch water at 4°C represents hydrostatic pressure from a 1-inch column of pure water at standard gravity, useful in HVAC and lab applications requiring fine pressure resolution.

How accurate is the conversion between decipascal and inch water?

The conversion assumes water density at 4°C and standard gravity; temperature or gravity changes can impact accuracy.
