What does nanopascal (nPa) measure?

Nanopascal (nPa) is a unit for very small pressure values equal to 10⁻⁹ pascals, used mainly in scientific and space applications.

Where is inch water (4°C) commonly used?

Inch water (4°C) is used for measuring low pressures in HVAC, ventilation systems, gas lines, and clean-room equipment.

How precise is the conversion between nanopascal and inch water (4°C)?

The conversion is based on a defined rate but requires caution due to the large scale difference between the units.
