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

Converting kilopascal to inch water (4°C) provides a finer pressure resolution useful in low-pressure environments like HVAC systems and laboratories.

Is the inch water unit affected by temperature?

Yes, the inch water measurement is specified at 4°C; changes in temperature can alter water density and thus affect accuracy.

Can this conversion be used for high-pressure measurements?

No, inch water (4°C) is suited only for low-pressure ranges; high-pressure measurements are better handled with kilopascal or other appropriate units.
