What does 1 inch water (4°C) represent?

It is the hydrostatic pressure from a 1-inch water column at 4 °C under standard gravity, used for measuring small pressures.

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

To express very low terrestrial pressure units in terms of extremely high pressures relevant in astrophysics and high-energy physics research.

Is this conversion commonly used in everyday applications?

No, it is mostly theoretical and used in specialized scientific fields due to the large difference in pressure scales.
