What is inch water (4°C) used for?

It measures low pressures with fine resolution, commonly in HVAC systems, laboratory manometry, and low-pressure gas lines.

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

Converting allows low-pressure readings to be expressed in a standard scientific unit useful for engineering analysis and material testing.

Is megapascal suitable for all pressure measurements?

Megapascal is ideal for high-pressure, stress, and material strength measurements, but not typically used for very low pressures.
