What does foot water (4°C) measure?

It measures the pressure from a 1-foot column of pure water at 4°C, commonly used for low-pressure and hydraulic head measurements.

Why convert foot water (4°C) to exapascal?

To relate typical low-pressure values in water systems to extremely large pressures relevant in astrophysics and high-energy physics research.

Is this conversion useful for everyday pressure measurements?

No, due to the vast difference in scale, it is mainly of academic interest and not for standard use.
