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

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

Why convert inch water (4°C) to newton per square millimeter?

To translate low-pressure values into standardized mechanical stress units common in engineering and materials science.

Can I use this converter for high pressure values?

No, inch water units are best for low pressures, and the conversion to newton/square millimeter results in very small values that may not be practical for high-pressure scenarios.
