What is a megapascal (MPa)?

A megapascal is a unit of pressure equal to one million pascals, used to measure mechanical stress and high-pressure levels in scientific and engineering contexts.

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

Inch water (4°C) is used for low pressure measurements requiring fine resolution, such as in HVAC systems, filtration monitoring, and sensitive laboratory pressure readings.

Can this converter handle very large pressure values?

Yes, it converts high-pressure values from MPa into small units of inch water, but the resulting numbers can be large and should be applied appropriately.
