What does an inch water (4°C) represent?

It is the pressure from a 1-inch column of pure water at 4 °C under standard gravity, commonly used for precise low-pressure measurements.

Why use microbar units in pressure measurement?

Microbars express very small pressures encountered in vacuum or sensitive atmospheric conditions where fine resolution is necessary.

Is the inch water to microbar conversion affected by temperature?

Yes, inch water pressure is defined at 4 °C, and changes in water temperature can slightly alter the pressure value.
