Why is the water temperature specified as 4°C in this pressure unit?

The millimeter water (4°C) represents the pressure exerted by a column of water at 4 °C, which is the temperature of maximum water density and standard conditions for this unit.

Can I use this conversion for high-pressure measurements?

No, millimeter water (4°C) is suitable for very low-pressure measurements and is not practical for high-pressure applications.

What industries commonly use this bar to millimeter water (4°C) conversion?

It is commonly used in meteorology, HVAC design, cleanroom control, laboratory research, and plumbing applications involving small pressure differentials.
